Object A has a charge q on it,object B has a charge q on it,and object C has a charge 2q on it.These charges are arranged,one each,at the vertices of an equilateral triangle.Which charge has the greatest magnitude electric force on it?

Question

Quizplus · Accepted Answer

The magnitude of the electric force between two charges is given by Coulomb's law: F = kq1q2/r^2, where k is a constant, q1 and q2 are the charges, and r is the distance between them. Since all three charges are the same distance apart from each other, the magnitude of the force depends only on the magnitude of the charges. Since object C has the largest charge (2q), it experiences the greatest magnitude of electric force. Therefore, choice C is the best answer.

Object a Has a Charge Q on It,object B Has
