Solution
The correct option is B STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is NOT a correct explanation for STATEMENT-1 Gravitational potential at inifinity Gi=0. Gravitational potential at r is Gr=−GMmr<0→Gr<Gi. Work done = change in gravitational potential energy. Thus , both the statements are true but 2 does not imply 1.
