Assume we are given an electric field set up
by an unknown charge distribution. U0 is
the amount of work needed to bring a point
charge of charge q0 in from infinity to a point P.
If the charge q0 is returned to infinity, how
much work would it take to bring a new charge
of 4 q0 from infinity to point P?
1. 4 U0
2.

2
5. 8 U0
6. More information is needed.
7. 2 U0
8. 0
9. U0
10. The correct answer is not given.
Is it 1,2,3,4,5,6,7,8,9, or 10?
Help is appreciated!
