4- Two very large parallel plates are separated by distance d. The plates carry equal but
opposite uniform surface charge densities. A point charge is placed between the
plates and has distance (d)/(2) from each of them. The point charge feels an electrical
force F. If this charge is moved closer to one of the plates so that it is a distance
0.343 d from that plate, what force will it feel?
2.92F
b) 1.46 F
(c) F
d) 0.343 F
e) 0.686 F
