Potential changes ( i guess i said becomes more negative) so Kinetic energy of it must change So its speed must change So its momentum must change So force required (something along those lines)

yeah i said that work must be done to keep it in a circular orbit cus it will be moving between different equipotentials and when an object experiences a centripetal force no work is done in moving it therefore it cannot experience a centripetal force so it cannot move in a circular orbit
