Physics - Error Question with Solution | TestHub

A negative point charge $-q$ of mass $m$ revolves around positive point charge $+Q$ which has very large mass compared to m so that it remains almost stationary. The only force acting on negative charge is the electrostatic force due to positive charge and the system forms a bounded system of negative energy with the charge +Q at one focus of the ellipse and negative charge tracing an ellipse at an instant shown in figure. Then which of the following statement is/are true?
