An alpha particle travels 5.00 cm in a uniform electric field of 6.00 x 10^2 N/C. (Alpha particles are made of two protons and two neutrons. mp= 1.673 x 10^-27 kg; mn=1.675 x 10^-27 kg; qe = 1.60 x 10^-19 C) A. What is the change in the potential energy of the particle? Does it increase or decrease? B. If the particle is initially at rest, what is the Kinetic Energy? C. What is its speed?
