Q.If the accelerating plates are 1.05 cm apart, and have a potential difference of 2.20×104 V, find the change in electric potential energy for an electron that moves from one accelerating plate to the other.

Q. A small object is attached to the end of a string to form a simple pendulum. The period of its harmonic motion is measured for small angular displacements and three lengths, each time clocking the motion with a stopwatch for 50 oscillations. For lengths of 1.000 m, 0.750 m, and 0.500 m, total time.
