Capacitance,&#8221; is covered in the Term I <a href=\"https:\/\/infinitylearn.com\/surge\/cbse\/cbse-syllabus\/\"><strong>CBSE Syllabus for 2024 25<\/strong><\/a>. This chapter holds significant weightage in the Term I exam, particularly when it comes to derivations and numerical problems.<\/p>\n<p>Exam questions often focus on deriving topics such as the potential energy of a system of charges, the potential due to an electric dipole, and the energy stored in a capacitor. Numerical questions based on the effective capacitance of complex capacitor combinations are also common.<\/p>\n<p>To help you master these concepts, the <strong>NCERT Exemplar Solutions for Class 12 Physics Chapter 2<\/strong> provide comprehensive coverage of all the topics in the chapter. These solutions can serve as a quick reference to clarify difficult concepts and improve your problem-solving skills.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"NCERT_Exemplar_Solutions_for_Class_12_Physics_Chapter_2_Electrostatic_Potential_and_Capacitance_Question_and_Answers\"><\/span>NCERT Exemplar Solutions for Class 12 Physics Chapter 2 Electrostatic Potential and Capacitance Question and Answers<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Q. Define electrostatic potential at a point.<\/strong><\/p>\n<p><strong>Ans:<\/strong> 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.<\/p>\n<p><strong>Q. What is the electrostatic potential due to a point charge Q at a distance r from it?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The electrostatic potential V due to a point charge Q at a distance r is given by:<br \/>\nV = (1 \/ 4\u03c0\u03b5\u2080) * (Q \/ r)<\/p>\n<p><strong>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?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The potential V at a distance r from a point charge +Q located at the origin is:<br \/>\nV = (1 \/ 4\u03c0\u03b5\u2080) * (Q \/ r)<\/p>\n<p><strong>Q. What is the principle of superposition for electrostatic potential?<\/strong><\/p>\n<p><strong>Ans:<\/strong> 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.<\/p>\n<p><strong>Q. Calculate the work done in moving a charge q through a potential difference V.<\/strong><\/p>\n<p><strong>Ans:<\/strong> The work done W in moving a charge q through a potential difference V is given by:<br \/>\nW = qV<\/p>\n<p><strong>Q. Define capacitance.<\/strong><\/p>\n<p><strong>Ans:<\/strong> Capacitance is defined as the ability of a system to store electric charge per unit potential difference. It is given by:<br \/>\nC = Q \/ V<br \/>\nwhere Q is the charge stored and V is the potential difference.<\/p>\n<p><strong>Q. What is the unit of capacitance?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The unit of capacitance is the Farad (F).<\/p>\n<p><strong>Q. Derive the expression for the capacitance of a parallel plate capacitor.<\/strong><\/p>\n<p><strong>Ans:<\/strong> The capacitance C of a parallel plate capacitor with plate area A and separation d is given by:<br \/>\nC = \u03b5\u2080 (A \/ d)<br \/>\nwhere \u03b5\u2080 is the permittivity of free space.<\/p>\n<p><strong>Q. What happens to the capacitance of a parallel plate capacitor if the plate separation is halved?<\/strong><\/p>\n<p><strong>Ans:<\/strong> 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.<\/p>\n<p><strong>Q. A capacitor of capacitance C is charged to a potential difference V. What is the energy stored in the capacitor?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The energy U stored in a capacitor is given by:<br \/>\nU = 1\/2 CV\u00b2<\/p>\n<p><strong>Q. What is the equivalent capacitance of two capacitors C\u2081 and C\u2082 connected in series?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The equivalent capacitance C\u2091 of two capacitors connected in series is given by:<br \/>\n1 \/ C\u2091 = 1 \/ C\u2081 + 1 \/ C\u2082<\/p>\n<p><strong>Q.. What is the equivalent capacitance of two capacitors C\u2081 and C\u2082 connected in parallel?<\/strong><\/p>\n<p><strong>Ans:<\/strong> The equivalent capacitance C\u2091 of two capacitors connected in parallel is given by:<br \/>\nC\u2091 = C\u2081 + C\u2082<\/p>\n<p><strong>Q. What is the potential at the midpoint of a dipole along its axial line?<\/strong><\/p>\n<p><strong>Ans:<\/strong> 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.<\/p>\n<p><strong>Q. A 4 \u03bcF capacitor is connected to a 12 V battery.
