CBSE Class 12 Physics Sample Paper 2024-25
Time Allowed: 3 hours | Maximum Marks: 80
General Instructions:
1. All questions are compulsory.
2. The question paper consists of 30 questions divided into four sections A, B, C, and D.
3. Section A contains 6 questions of 1 mark each.
4. Section B contains 6 questions of 2 marks each.
5. Section C contains 10 questions of 3 marks each.
6. Section D contains 8 questions of 4 marks each.
7. Use of calculators is not permitted.
1) A uniform electric field directed along the positive X-axis is present in a certain region. Let A be the origin, B be the point on the X-axis at x = +1 cm, and C be the point on the Y-axis at y = +1 cm. Then the potential at points A, B, and C satisfy.
Answer: (B) VA > VB
Explanation: The electric potential decreases in the direction of the electric field. Since the electric field points in the positive X-direction, point B (on the X-axis) will have a lower potential compared to point A (the origin).
2) A conducting wire links two charged spherical conductors with radii r1 and r2, allowing them to reach electrostatic equilibrium. The distance of separation between the two spheres is very large as compared to either of their radii. The ratio of the magnitudes of the electric fields at the surfaces of the spheres of radii r1 and r2 is
Answer: (B) r2/r1
Explanation: The electric field at the surface of a conducting sphere is given by E = (1 / (4πϵ₀)) * (Q / r²)
Since the spheres are in equilibrium, their surface charges are proportional to their radii, so the ratio of electric fields is inversely proportional to the ratio of their radii.
3) A long straight wire of circular cross-section of radius ‘a’ carries a steady current I. The current is uniformly distributed across its cross-section. The ratio of magnitudes of the magnetic field at a point a/2 above the surface of the wire to that of a point a/2 below its surface is
Answer: (B) 1:1
Explanation: The magnetic field inside the wire is directly proportional to the distance from the center, while outside the wire, the magnetic field is inversely proportional to the distance. Therefore, the magnetic fields at these points are the same.
4) The diffraction effect can be observed in
Answer: (D) Sound waves as well as light waves
Explanation: Diffraction occurs when waves encounter obstacles or slits comparable in size to their wavelength. Both sound and light waves can experience diffraction.
5) A capacitor consists of two parallel plates, with an area of cross-section of 0.001 m², separated by a distance of 0.0001 m. If the voltage across the plates varies at the rate of 10⁸ V/s, then the value of the displacement current through the capacitor is
Answer: (B) 8.85 × 10^−4 A
6) In a series LCR circuit, the voltage across the resistance, capacitance, and inductance is 10 V each. If the capacitance is short-circuited, the voltage across the inductance will be
Answer: (D) 20 V
Explanation: When the capacitance is short-circuited, the inductance will carry the total voltage, which would be double the voltage across the inductance originally, resulting in 20 V.
7) The distance of closest approach of an alpha particle is ‘d’ when it moves with a speed ‘V’ towards a nucleus. Another alpha particle is projected with higher energy such that the new distance of the closest approach is ‘d/2’. What is the speed of projection of the alpha particle in this case?
Answer: (C) 2V
Explanation: The distance of closest approach is inversely proportional to the speed of the alpha particle. If the distance is halved, the speed must double.
8) A point object is placed at the center of a glass sphere of radius 6 cm and refractive index 1.5. The distance of the virtual image from the surface of the sphere is
Answer: (B) 4 cm
Explanation: Using the formula for refraction and considering the sphere as a medium, the image formed would be at a distance of 4 cm from the surface.
9) Colours observed on a CD (Compact Disk) is due to
Answer: (B) Diffraction
Explanation: The observed colors on a CD are due to diffraction of light as it interacts with the grooves on the disk.
10) The number of electrons made available for conduction by dopant atoms depends strongly upon
Answer: (D) Options (A) and (B) both
Explanation: The number of conduction electrons depends both on the doping level and the temperature of the material.
11) A beam of light consisting of two wavelengths, 4000 Å and 6000 Å, is used to obtain interference fringes in a Young’s double-slit experiment. What is the least distance from the central maximum where the dark fringe is obtained?
Answer: (The question requires calculation based on the fringe formula.)
12) In Young’s double-slit experiment using monochromatic light of wavelength λ, the intensities of two sources are I. What is the intensity of light at a point where the path difference between wavefronts is λ/4?
Answer: (Intensity calculation based on the interference formula.)
13) Derive the formula for the capacitance of a parallel plate capacitor with plate area A and separation distance d, when:
(I) A dielectric material of thickness t is inserted between the plates. (II) A metallic slab of thickness t is placed between the plates, where (t < d) are introduced one by one between the plates of the capacitor. In which case would the capacitance be more and why?
Answer:
Case I: The capacitance increases with the introduction of a dielectric slab as it increases the permittivity between the plates.
Case II: A metallic slab would cause a short-circuit between the plates, hence reducing the capacitance.
Therefore, the capacitance will be more in the case of the dielectric slab.
14) (I) Draw a ray diagram for the formation of image by a Cassegrain telescope.
(II) Why are reflecting telescopes favored over refracting telescopes? (Provide two reasons).
Answer:
Ray Diagram for Cassegrain Telescope:
(The diagram would show the light entering through the primary mirror, reflected to the secondary mirror, and then focused at the focal point.)
Why Cassegrain Telescopes are Preferred:
Compact Design: Cassegrain telescopes are more compact than refracting telescopes due to the use of a curved mirror system instead of lenses.
No Chromatic Aberration: Since mirrors are used instead of lenses, there is no chromatic aberration in Cassegrain telescopes, unlike refracting telescopes.
