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....

Simply calculate the ΔV because that times q is your work.

so i used V= Ke q/r?
