A uniform electric field is established by connecting the plates of a parallel-plate capacitor to a 12.0 V battery.
(a) If the plates are separated by 0.50 cm, what is the magnitude of the electric field in the capacitor?
(b) A charge of -5.25×10-6 C moves from the negative plate to the positive plate. Find the change in electric potential energy for this charge.
(c) Suppose the charge in (b) is released from rest, and it reaches the positive plate with a speed of 4.20 m/s. What is the mass of the charge and its final kinetic energy?
