Question

Calculate the work done in taking a charge of 0.02c forth A to B . If the potential at A is 20V ,and that at B is 30V.

Answer 1

Work done in moving a charge q from pointA to point B with a potential difference V is given by..........

W=qV

Here q=0.02C
V=30-20=10

so .....
W=0.02×10
W=0.2J
