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.

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

Explanation:

See picture

vapour or gas assuming atmospheriv pressure

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
