a. Define what is meant by the electric field strength at a point.
In a particle accelerator, a proton, initially at rest, is accelerated between two metal plates, as shown.

b. Calculate the force on the proton due to the electric field.
c. Calculate the work done on the proton by the electric field when it moves from plate A to plate B.
d. State the energy gained by the proton.
e. Assuming that all this energy is converted to kinetic energy of the proton, calculate the speed of the proton when it reaches plate B.

(Charge on a proton = +1.6 × 10⁻¹⁹ C; mass of a proton = 1.7 × 10⁻²⁷ kg.)
