A charge +3q is placed at x = 0 and a charge +11q is placed at x = 5 units. Where, along the x-axis is the net force on a charge Q equal to zero?

Question

Quizplus · Accepted Answer

The net force on charge Q will be zero where the forces due to +3q and +11q are equal in magnitude and opposite in direction. Using Coulomb's law and setting the forces equal, we find the position x = 1.72 units.
