Question

A proton is released from rest in a uniform electric field which is directed along the x axis and of magnitude E=2*10exponent5 V/m.The proton undergoes a displacement from point A at the origin to point B at x=0.2m.What is the change in the potential energy of the proton between points A and B?

Answer 1

Remember that energy is conserved, so Ek + Ep will always equal Etotal.
