NEET Physics Gravitational Potential Energy Assertion Reason Question
Assertion (A): The gravitational potential energy of a particle at a point outside the Earth is always negative.
Reason (R): The work done in moving the particle from infinity to that point is defined as its gravitational potential energy.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The gravitational potential energy is negative because it is defined relative to a point at infinity where potential energy is zero, and the work done in moving a particle from infinity to a point outside the Earth is negative.
