Question

The drawing shows a square, each side of which has a length of L = 0.25 m. Two different positive charges q1 and q2 are fixed at the corners of the square. Find the electric potential energy of a third charge q3 = -7 x 10-9 C placed at corner A and then at corner B.

Explanation / Answer

1) EPA_A = k*q1*q3/L +k*q1*q2/L +k*q2*q3/L*sqrt*2

2)EPA_B = k*q2*q3/L +k*q1*q2/L +k*q1*q3/L*sqrt*2
