Question

In the figure four particles form a square q4 = -25q

Answer 1

The net Coulomb force on the charge q at the center of the square is zero when the charges on the four corners are exactly equal.

Step-by-step explanation:

The question is asking about the net Coulomb force on the charge q at the center of a square, given that there are four particles at the corners of the square. The charges on the four corners are given as qc and qd. To determine the net force, we need to consider the direction and magnitude of the forces due to each charge. Since the charges on the four corners are exactly equal, the net Coulomb force on the charge q at the center of the square is zero.
