## Homework Statement

+1.0uC

*-------3.0m---------*-----------3.0m---------*

A B

a) calculate the electric potential energy at A, 3.0m away from a point charge of +1.0uC.

b) calculate the electric potential energy at B, 6.0m away from a point charge of +1.0uC.

c) how much work would be done moving a +0.2uC charge between A and B?

d) which way would you be moving this smal charge if you were doing work against the field?

## Homework Equations

V=kQ/r

W-qV

## The Attempt at a Solution

a)

V=kQ/r

V= 8.99 x 10^9 x 1.0 / 3 = 2996666667N

b)

V=kQ/r

V=8.99 x 10^9 x 1.0 / 6 = 1498333333N

c)

W=qV

W= 8.99 x `10^9 x .2

W = 1798000000

d)

to the right.

I'm not sure if I'm on the right track, can anyone check and help me?
