Question

If a box of mass 25 kg is pushed 15 m by a force of ‘F’ N, work done in the process is 480 J. Find F:
1. 50
2. 32
3. 16
4. 25

Answer 1

Correct Answer - Option 2 : 32

The correct answer is 32.

Given:

Mass= 25 kg.

Distance= 15 m.

Work= 480 J.

Calculation:

\(Work = Force \times Distance\)

∴ 480= \(F\times 15\)

F= \(480\over15\)= \(32\ N\)

Force= 32 N.
