If two charges are not changed but they are moved twice farther than the original distance r, what becomes of the new electric force?

A proton Q = +e and an electron Q = -e are in a constant electric field created by oppositely charged plates. You release the proton from near the positive plate and the electron from near the negative plate. Which feels the larger electric force? O The electron. O The proton. O Neither-there is no force. O The magnitude of the force is the same for both and in the same direction. O The magnitude of the force is the same for both but in opposite directions.

A point charge located at the origin generates an electric field that has the value E = (830 N/C) i + (150 N/C) j at the point (x, y) = (2.50 m, 3.20 m). What is the value of the charge?

The figure shows 2 charges q1= 1.5 MC and q2=2.3 MC separated by L=13 cm At what point x, E=0?
