Question 56: Waves

Question

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):

Accepted Answer

We have,
$$\overrightarrow J  = \overrightarrow r  	imes \overrightarrow F $$
$$|\overrightarrow J | = rF\sin 180^\circ  = 0$$
Therefore, the angular momentum is conserved, that is,
$$mvr\sin 	heta  = $$ Constant
where $$	heta$$ is the angle between the velocity $$\overrightarrow v $$ and position vector $$\overrightarrow r $$ of $$-$$q with respect to Q.

Answer

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

Answer

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

Answer

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

Answer

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