Consider a negatively charged particle entering a region betweentwo large charged plates, as shown in the diagram below. Theinitial velocity of the particle is 7.0 x 10^7 m/s. The mass of theparticle is 9.1 x 10^-31kg and the charge is -1.6 x 10^-19C. Thedistance between the plates is 0.025m. You can consider theelectrical force to be the only force acting between the plates.(The force of gravity is negligible and can be considered to bezero in this problem.)

a) Determine the magnitude and the direction of the electric field,if the particle just reaches the negative plate (if the velocity atthe negative plate is zero). Show your work and explain yourreasoning.
b) Determine the potential difference between the plates. Show yourwork and explain your reasoning.
c) Which plate is at a higher potential. Show your work and explainyour reasoning.
