1. The problem statement, all variables and given/known data

1. A +38 uC charge is place @ 41cm from an identical +38uC. If assuming the potential identity is 0. whats the potential midway btw the 2 charges?

2. How much work is done to move a 0.40 uC charge from a point midway between the charge to a point 10 cm closer to either of the charges?

2. Relevant equations

V= m/q ?

F= Ke qq/r

3. The attempt at a solution

Not sure where to start but....

8.99e-19(38e-6)(q3)/(.041m-x )^2

8.99e-19(38e-6)(q3)/(x )^2
