Asked by Willow
Two charges are located along the x-axis. One has a charge of 6.3 μC, and the second has a charge of −3.4 μC.
If the electrical potential energy associated with the pair of charges is −0.043 J,what is the distance between the charges? The value of the Coulomb constant is 8.98756 × 109 N · m2/C2 , and the acceleration due to gravity is 9.81 m/s2 .
Answer in units of m
Thank you

Each has 1/2 the total PE.
So looking at the charges...
.043/2= kQ1Q2/r solve for r.

@bobpursley is right, but don't divide potential energy by 2
