Electrostatic Potential Energy

90 J of work is done to move an electric charge of magnitude 3 C from a place A, where potential is -10 V to another place B, where potential is ' $V_1$ ' volt. The value of $V_1$ is

Show answer and solution

Answer: (b)

$W = q(V_B - V_A)$
$90 = 3(V_1 + 10) \Rightarrow V_1 + 10 = 30$
$V_1 = 20$ V. So the answer is (b).
