Question

state the principle of superposition and use it to obtain the expession for the total force exerted on a point charge due to an assembly of (N-1) discrete point charges​

Answer 1

Answer:

Principal of superposition states that the force on a point charge due to some other point charge remains unchanged. The only thing which changes is the net force on a point charge due to introduction of third charge.

According to principal of superposition,

Force on charge at n= Force on charge due to 1+Force on charge due to 2+Force on charge due to 3+..............+Force on charge due to N-1+
