This question is similar to the one that I posted previously:(adsbygoogle = window.adsbygoogle || []).push({});

Two point charges each of magnitude 2.09 micro Coulombs, are located on the x-axis. One is at x=1.38 m and the other is at x=-1.38 m.

a) Determine the electric potential on the y-axis at y=0.511 m.

b) Calculate the electric potential energy of a third charge, of -3.08 micro Coulombs, placed on the y-axis at y=0.511 m.

I used the same approach for this question as I did for the other question that I posted, i.e. using the summation of Coulomb's Law and various other creative yet ineffective approaches. Any help would be greatly appreciated. Thanks!
