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?
