NCERT Exemplar Solutions for Class 12 Physics Chapter 2 Electrostatic Potential and Capacitance Question and Answers
Q. Define electrostatic potential at a point.
Ans: The electrostatic potential at a point is defined as the amount of work done in bringing a unit positive charge from infinity to that point without acceleration.
Q. What is the electrostatic potential due to a point charge Q at a distance r from it?
Ans: The electrostatic potential V due to a point charge Q at a distance r is given by:
V = (1 / 4πε₀) * (Q / r)
Q. A point charge +Q is located at the origin. What is the potential at a point located at a distance r from the origin?
Ans: The potential V at a distance r from a point charge +Q located at the origin is:
V = (1 / 4πε₀) * (Q / r)
Q. What is the principle of superposition for electrostatic potential?
Ans: The principle of superposition states that the total electrostatic potential at a point due to a system of charges is equal to the algebraic sum of the potentials due to the individual charges.
Q. Calculate the work done in moving a charge q through a potential difference V.
Ans: The work done W in moving a charge q through a potential difference V is given by:
W = qV
Q. Define capacitance.
Ans: Capacitance is defined as the ability of a system to store electric charge per unit potential difference. It is given by:
C = Q / V
where Q is the charge stored and V is the potential difference.
Q. What is the unit of capacitance?
Ans: The unit of capacitance is the Farad (F).
Q. Derive the expression for the capacitance of a parallel plate capacitor.
Ans: The capacitance C of a parallel plate capacitor with plate area A and separation d is given by:
C = ε₀ (A / d)
where ε₀ is the permittivity of free space.
Q. What happens to the capacitance of a parallel plate capacitor if the plate separation is halved?
Ans: If the plate separation d is halved, the capacitance C is doubled. This is because capacitance C is inversely proportional to the plate separation d.
Q. A capacitor of capacitance C is charged to a potential difference V. What is the energy stored in the capacitor?
Ans: The energy U stored in a capacitor is given by:
U = 1/2 CV²
Q. What is the equivalent capacitance of two capacitors C₁ and C₂ connected in series?
Ans: The equivalent capacitance Cₑ of two capacitors connected in series is given by:
1 / Cₑ = 1 / C₁ + 1 / C₂
Q.. What is the equivalent capacitance of two capacitors C₁ and C₂ connected in parallel?
Ans: The equivalent capacitance Cₑ of two capacitors connected in parallel is given by:
Cₑ = C₁ + C₂
Q. What is the potential at the midpoint of a dipole along its axial line?
Ans: The potential at the midpoint of a dipole along its axial line is zero because the potentials due to the positive and negative charges cancel each other out.
Q. A 4 μF capacitor is connected to a 12 V battery. What is the charge stored in the capacitor?
Ans: The charge Q stored in the capacitor is given by:
Q = CV = 4 × 10⁻⁶ F × 12 V = 48 × 10⁻⁶ C = 48 μC
Q. Two capacitors of capacitances 6 μF and 3 μF are connected in series. What is their equivalent capacitance?
Ans: The equivalent capacitance Cₑ of capacitors connected in series is given by:
1 / Cₑ = 1 / 6 + 1 / 3 = 1 / 6 + 2 / 6 = 3 / 6 = 1 / 2
Therefore, Cₑ = 2 μF.
