#### Solution Preview

Electric filed strength at a point is the force per unit test charge.

The field strength due to a point charge Q at distance r from the charge is given by the equation (using coulombs law)

#### Solution Summary

The problem shows three equal charges that are placed at the three corners of a square and equal negative at the fourth one. The magnitude and direction of the resulting field at the center of the square is calculated.
