Question

A uniformly charged thin ring has radius 14.0 cmand total charge 22.0 nC . An electron is placed on the ring's axis a distance 34.5 cm from the center of the ring and is constrained to stay on the axis of the ring. The electron is then released from rest.

Part A Describe the subsequent motion of the electron.

Part B Find the speed of the electron when it reaches the center of the ring.

Answer 1

Answer:

a. The Electron will begin to move along the axis, towards the center and velocity of it is instantaneous because the force acting on it depends on x and the acceleration as well until it reaches maximum velocity at the center.

b. Vb= 1.6 * 10^7 m/s^2
