a) determine the electrostatic potential energy of a system consisting of two charge 7 uC and -2uC

a) determine the electrostatic potential energy of a system consisting of two charge 7 uC and -2uC (and with no external field) placed at (-9cm,0,0) and (9cm,0,0) respectively.
b) how much work is required to separate the two charge infinitely away from each other?
c) suppose that the same system of charges now place in an external electric field E= A(1/r²);A=9 ×10 ⁵ cm -². What was the electrostatic energy of the configuration be ?
