Answer #1

Given the two charges are qA = 4C, qB = 4C and the side of the equilateral triangle is r = 3m. The electric potential at C due to A is given by,

The electric potential at C due to B is given by,

The total potential at C is given by,

So the total potential at C is 24.2kV.

Option (b) is the correct answer.
