Question
Why does the gravitational force provide the necessary centripetal force for a circular orbit?
Explanation
In a circular orbit, the gravitational force (GMEmr2) equals the centripetal force (mv2r), providing the inward force needed to maintain circular motion. As per NCERT, applying relevant law/formula with correct units and sign convention leads to It balances the required inward force. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
