A particle with a charge of 4.50nC is in a uniform electric field directed to the left. It is released from rest and moves to the left; after it has moved 8.00cm , its kinetic energy is found to be 1.50×10?6 J.
a) What work was done by the electric force?
b) What is the potential of the starting point with respect to the endpoint?
c) What is the magnitude of E?
