Given below are two statements:
| Assertion (A): | The work done on bringing a body down from the top to the base along a frictionless inclined plane is the same as the work done in bringing it down the vertical side. |
| Reason (R): | The gravitational force on the body along the inclined plane is the same as that along the vertical side. |
| 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. |
