a parallel plate capacitor creates an electric field of strength 10N/C between its plates, which are separated by 10mm. If a small sphere with charge 2 nC and mass of 20 g is held next to the positive plate, what is the force on that sphere? What will the acceleration of the sphere be? how long will it take to reach the other plate? What will its speed be when it reaches the other plate?

Imagine a parallel plate capacitor with mica between the plates.   Suppose the potential difference between the plates is 82V, and there is an electric field between the plates with a strength of 320 N/C.  If each plate has an area of 0.030 square meters,   a)  What is the separation between the plates? b)  Find the capacitance of the capacitor. c)  How much charge is on each plate? d)  How much energy is stored in the capacitor?   For each part, explain your reasoning.

A proton (mass = 1.67 x 10-27 kg, charge = 1.60 x 10-19 C) moves from point A to point B under the influence of an electrostatic force only. At point A the proton moves with a speed of 50 km/s.
