NEET Physics Gravitational Potential Energy MCQ Question
In the diagram shown above, if a particle of mass m is moved from point A at distance r1 from the center of the Earth to point B at distance r2 (where r2 > r1), how is the work done related to the gravitational potential energy change?
The work done is equal to the negative change in gravitational potential energy.
The work done is equal to the change in gravitational potential energy.
The work done is zero since gravitational potential energy does not change.
The work done is equal to the gravitational force times the distance (r2 - r1).
Correct Answer
Detailed Explanation
According to the NCERT context, the work done on a particle moving from r1 to r2 under gravity is related to the change in gravitational potential energy by W = -(W(r2) - W(r1)).
