Under the influence of the Coulomb field of charge `+Q`, a charge `-q` is moving around it in an elliptical orbit. Find out the correct statement (s)

A

The angular momentum of the charge `-q` is constant

B

The linear momentum of the charge `-q` is constant

C

The angular velocity of the charge `-q` is constant

D

The linear speed of the charge `-q` is constant

Text Solution

Verified by Experts

The correct Answer is:
A
Since torque about central charge is zero angular momentum is conserved.
