Official UPSC Answer KeyUPSC Prelims 1996 • Science and Technology

Correct Answer: Option (B) — the same amount of work with lesser force

Concept & Option Breakdown

Standard Reference Verified

A simple machine (such as a lever, pulley, or inclined plane) does not reduce the total amount of mechanical work required ($W = \text{Force} \times \text{Distance}$). Instead, it provides mechanical advantage by reducing the required input effort force while increasing the distance over which that force must be applied.

Elimination Heuristic & Exam Approach

Conservation of energy dictates work cannot be reduced; simple machines only reduce the required effort force by trading it for distance.
