Question

State whether the magnitude of the net electric force on the charge labeled+O in case A is greater than, less than, or equal to the magnitude of the net electric force on the charge labeled +O in case B. Explain how you determined your answer. Need help please 7. State whether the magnitude of the net Case A Neutral metal cube Case B electric force on the charge labeled +Q,in case A is greater than, less than, or equal to the magnitude of the net electric force on the charge labeled +Q, in case B. Explain how you determined your answer. -0 -0 meta' plate k=c G wh ce-dist

Explanation / Answer

First of all Fb>Fa as you can see using answer and the reason because of which force on charge increases when metal plate is placed between them is because the effective distance between two charges decreases.

x/k is the effective distance of metal which we can assume the distance in air.distance which is used in formulla is distance in air between to charged particles.

hope it helps.
