A particle of charge +3.0 x 10-8 is in a unifromelectric field directed to the left. It is released from rest andmoves a distance of 5.0 cm and its kinetic energy is increased by+4.5 x -4 J.
a) What is the work fone by the electric force?
b) What is the magnitude of the electric field?
c) What is the electric potential of the starting point relative tothe endpoint of the path?
