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$(s)$.

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

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

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

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

(IIT-2009)

Solution

The correct option is $A$ The angular momentum of the charge $- q$ is constant Given that a charge $- q$ mover under the influence of a coulombic field of charge $+ A$. The charge $- q$ moves in an elliptical orbit. Therefore, the angular momentum of the charge $- q$ about charge $+ A$ is constant, since the torque on the charge is zero.

A body having specific charge $8\,\mu {C} / {g}$ is resting on a frictionless plane at a distance $10\, {cm}$ from the wall (as shown in the figure). It starts moving towards the wall when a uniform electric field of $100 \,{V} / {m}$ is applied horizontally toward the wall. If the collision of the body with the wall is perfectly elastic, then the time period of the motion will be $….\, S.$
