Assertion (A): | Work done by the gravitational force is positive when two point masses are brought from infinity to any two points in space. |
Reason (R): | Gravitational potential energy increases during the above process. |
1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
3. | (A) is true but (R) is false. |
4. | Both (A) and (R) are false. |
Assertion (A): | The gravitational potential energy associated with a particle-earth system depends on the vertical position (or height) of the particle relative to the reference position, not on the horizontal position. |
Reason (R): | For any height h above earth's surface, the potential energy of the particle is mgh |
