Two parallel plates having charges of equal magnitude but opposite sign are separated by 16.0 cm. Each plate has a surface charge density of 48.0 nC/m2. A proton is released from rest at the positive plate.

(a) Determine the magnitude of the electric field between the plates from the charge density.
kN/C

(b) Determine the potential difference between the plates.
V

(c) Determine the kinetic energy of the proton when it reaches the negative plate.
J

(d) Determine the speed of the proton just before it strikes the negative plate.
km/s

(e) Determine the acceleration of the proton.
m/s2 towards the negative plate

(f) Determine the force on the proton.
N towards the negative plate

(g) From the force, find the magnitude of the electric field.
kN/C

(h) How does your value of the electric field compare with that found in part (a)?
