12 J of work has to be done against an existing electric field to take a charge of 0.01 C from A to B. How much is the potential difference VB – VA?

Answer :

Work done against electric field: W= 12 J
Charge : q= 0.01 C
Formula used:
Work done is given by:
W=Potential difference×charge

W=(VB-VA )×q
Here, VB-VA is the potential difference and q is the charge.

Hence, potential difference is 1200 V
