In raising an object to given height by means of an inclined plane, as compared with raising the object vertically, there is a reduction in
General SciencePhysics
- AForce to be applied
- BWork required
- CDistance covered
- DFriction force
Explanation
On an inclined plane the force required is reduced by the mechanical advantage (a force × distance trade-off), while the work done against gravity (mgh) is unchanged ignoring friction, and the distance travelled is greater. Hence the reduction is in the force to be applied — option (A).
