Question

If the electric potential between two points A and B is 2V and 4V respectively. Then, how much work isdone in bringing a point charge of 8μC from point A to point B ?

Solution
Verified by Toppr

q0=8μC
q0=8×106C
Potential differnce between A and B
VBVA=WABq0
42=WAB8×106
WAB=2×8×106
WAB=16×106J
WAB=1.6×105J
