A charged particle is caused to move between two electrically charged plates, as shown here.

(a)Why does the path of the charged particle bend?
(b)What is the sign of the electrical charge on the particle?
(c) As the charge on the plates is increased, would you expect the bending to increase, decrease, or stay the same?
(d) As the mass of the particle is increased while the speed of the particles remains the same, would you expect the bending to increase, decrease, or stay the same?
