A charged particle travels through a small hole in plate A and then towards plate B. There is a uniform electric field between the plates.
- Part (a)* The particle is a proton. The field slows down the proton without deflecting it. What is the direction of the electric field? Choose the best answer. 1) Left 2) Up 3) Down 4) Right
- Part (b)* The particle is an electron. The field slows down the electron without deflecting it. What is the direction of the electric field? Choose the best answer.
1) Right 2) Up 3) Down 4) Left
- Part (c)* The field is pointing from A to B and the particle speeds up without being deflected. What kind of particle could it be?? Choose the best answer.
1) Na^+ ion 2) Cl^- ion 3) Electron 4) Neutron
