Question

Three point charges exist along the x-axis. A charge of +e is at the origin, a charge of -4 e exists 2 μm to the left of the origin, and another charge of +4 e exists 2 μm to the right of the origin. Calculate the net force on the rightmost charge.

Answer #1

Let the net force on the rightmost charge is F.

Let the force due to the leftmost charge is F_{L}.

Let the force due to charge on the origin is F_{R.}

The force due to the leftmost charge is

The force due to the charge on the origin is

Now the net force on the rightmost charge is

The net force on the rightmost charge is 0 N.

=>Comment in case any doubt...........
