A particle with a charge of +4.30 nC is in a uniform electric field E⃗ directed to the negative x direction. It is released from rest, and after it has moved 8.00 cm , its kinetic energy is found to be 1.50×10−6 J .
A. What work was done by the electric force?
Express your answer in joules to three significant figures.
B. What was the change in electric potential over the distance that the charge moved?
Express your answer in volts to three significant figures.
C. What is the magnitude of E⃗ ?
Express your answer in volts per meter to three significant figures.
D. What was the change in potential energy of the charge?
Express your answer in volts per meter to three significant figures.
