NEET Physics (general) MCQ Question
Which of the following statements about electrostatic potential and capacitance are correct?
Inserting a dielectric material between capacitor plates increases capacitance while connected to a voltage source.
The electrostatic energy stored in a capacitor is independent of the voltage applied across it.
The work done in bringing a charge to a point in an electric field depends on the path taken.
A disconnected capacitor retains the same charge regardless of its arrangement with other capacitors.
Correct Answer
Detailed Explanation
Statement A is correct as inserting a dielectric increases capacitance when voltage is maintained. Statement B is incorrect because electrostatic energy is directly related to the voltage. Statement C is misleading since work done is path-independent in electrostatics. Statement D is incorrect because connecting to another capacitor can redistribute charge.
