Problem 78GP
Find the difference in electric potential, ΔV = VB — VA between the points A and B for the following cases: (a) The electric field does 0.052 J of work as you move a +5.7-μC charge from A to B. (b) The electric field does -0.052 J of work as you move a −5.7-μC charge from A to B. (c) You perform 0.052 J of work as you slowly move a +5.7-μC charge from A to B.

(b) The electric field does -0.052 J of work as you move a −5.7-μC charge from A to B. (c) You perform 0.052 J of work as you slowly move a +5.7-μC charge from A to B.
ANSWER:
Solution 78 GP:
Step 1 of 3:-
a)
Here, we have to find the potential difference between a and B, if the electric field does 0.052 J of work as you move the charge from A to B.
We know that,
