In an electric field due to charge Q, a charge q moves from point A to B as shown in the figure. The work done is ( ε₀ = permittivity of free space) (a) (1)/(4πε₀)Qq/r² (b) (1)/(4πε₀)Qq/r²π/6 (c) (1)/(4πε₀)Qq/r (d) zero

Answer: (d). A and B both lie at distance r from Q (same circle), so VA = VB = kQ/r. W = q(VB - VA) = 0 So the answer is (d) zero.

Electrostatic Potential Energy

In an electric field due to charge $Q$ , a charge $q$ moves from point A to B as shown in the figure. The work done is ( $\varepsilon_0 =$ permittivity of free space)

Show answer and solution

Answer: (d)

A and B both lie at distance $r$ from $Q$ (same circle), so $V_A = V_B = \dfrac{kQ}{r}$ .
$W = q(V_B - V_A) = 0$
So the answer is (d) zero.
