Vedclass · Answer

(A) The electrostatic force between the charges $+Q$ and $-q$ is a central force,which acts along the line joining the two charges.Since the force is central,the torque $\vec{	au} = \vec{r} 	imes \vec{F}$ about the position of charge $+Q$ is zero.According to the principle of conservation of angular momentum,if the net torque is zero,the angular momentum $\vec{L}$ remains constant.In an elliptical orbit,the distance between the charges changes continuously,which causes the magnitude of the electrostatic force to change.Consequently,the linear speed and the linear momentum of the charge $-q$ are not constant.Additionally,since the distance from the center changes,the angular velocity is also not constant.

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$(s)$.
