An electric field of 120 N/C is maintained between two plates separated by 10.0 cm. A positive charged particle of mass 1.92 x 10-20 kg is placed at the positive plate and released. If its speed at the negative plate is 21,000 m/s, find:

a)the work done on the charge.

b)the potential difference between the plates

c) the charge on the particle.

Show all the steps and state the answer as clear as possible please. Thank you.
