Question

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?

Answer 1

Answer 2

I need to know the direction of the electric field

Answer 3

I think its the right

Answer 4

ALso need to know which way did it travel?
surely there is a diagram somewhere
