Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Potential due to a dipole | (i) V = k * (p.r) / r^2 |
| (b) Work done on moving a charge | (ii) U = -k * (q1*q2)/r |
| (c) Electric field from surface charge | (iii) E = σ / ε0 |
| (d) Potential energy in a field | (iv) W = q * V |
A
a-i, b-iv, c-iii, d-ii
B
a-ii, b-iii, c-i, d-iv
C
a-iv, b-i, c-ii, d-iii
D
a-iii, b-ii, c-iv, d-i
Correct Answer
Option A
Detailed Explanation
The potential due to a dipole is given by the expression V = k * (p.r) / r^2, where p is the dipole moment. The work done on moving a charge is calculated using W = q * V, which relates the potential to the work done. The electric field from a surface charge is defined as E = σ / ε0, and the potential energy in a field is given by U = -k * (q1*q2)/r.
