A particle with a charge of 4.10nC is in a uniform electric field E? directed to the left. It is released from rest and moves to the left; after it has moved 6.00cm , its kinetic energy is found to be 1.50×10?6J .
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?
