Which of the following statements are correct about a satellite moving around a planet in an elliptical orbit ?

A charge q is moving in a magnetic field then the magnetic force does not depend upon

Write formula for moving charge q in magnetic field.

If a charge is moved against the coulomb force of an electric field, then

If a charge is moved against the Coulomb force of an electric field

A positive point charge +Q is fixed in space .A negative point charge -q of mass m revolves around a fixed charge in elliptical orbits .The fixed charge +Q is at one focus of the ellipse.The only force acting on negative charge is the electrostatic force due to positive charge is the electrostatic force due ot positive charge.Then which of the following statement is true
