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?
A) A
B) C
C) B
D) All have equal magnitude forces on them.

Question

Quizplus · Accepted Answer

The magnitude of the electric force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. In this case, the distance between any two charges is the same, so the magnitude of the force depends only on the product of the charges. Since object C has the largest charge (2q), it will experience the greatest magnitude force. Therefore, choice B is the best answer.

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