NEET Physics Electric Potential Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Electric potential at a point | (i) Work done per unit charge |
| (b) Potential due to a point charge | (ii) V = kQ/r |
| (c) Potential inside a cavity | (iii) Always zero |
| (d) Electrostatic shielding | (iv) Charges reside on outer surface |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-ii, d-i
a-iii, b-iv, c-i, d-ii
Correct Answer
Detailed Explanation
The electric potential at a point is defined as work done per unit charge (i). The potential due to a point charge is given by V = kQ/r (ii). Inside a cavity of a conductor, the potential is always zero (iii). Electrostatic shielding implies that charges reside only on the outer surface of the conductor (iv).
