Question

A 0.5 kg, +2 C point charge is shot through an opening in middle of one of the plates in a parallel plate system at 20 m/s. If the point charge barely makes it to the opposite plate, what is potential difference through which it travels between the parallel plates? and please show the work
A) -100 J/C
B) -50 J/C
C) 0 J/C
D) +50 J/C
E) +100 J/C

Expert Solution
Step 1

Given:

Mass = 0.5 kg

Charge q = +2 C

Velocity (final) v = 20 ms

Formula used:

v2 - u2 = 2as  .....(1)

Initial velocity = 0

s is the distance.

a = qEm ....(2)

V (potential difference) = E × s .....(3)
