Charge A has 10 electric field lines coming out,Charge B has 20 lines coming out,and Charge C has 30 lines coming in.Which pair of these charges will have the largest force between them if placed one cm apart?

Question

Quizplus · Accepted Answer

The force between two charges is proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. Therefore, the force between Charges A and B will be (10 x 20)/(1^2) = 200, the force between Charges B and C will be (20 x 30)/(1^2) = 600, and the force between Charges C and A will be (30 x 10)/(1^2) = 300. Therefore, the greatest force will be between Charges B and C.
