Question

One joule work is said to be done when a force of one newton acts through a distance of

• A. 1 cm
• B. 1 mm
• C. 1 m
• D. 1 km

Answer 1

The correct option is C

1 m

Explanation for the correct option :

1. 1 Joule is defined as the amount of work done when 1 N of force is applied and the displacement of the body is 1 m.
2. The SI unit of force (F) is Newton and displacement (s) is m,
   1 J = 1 N x 1 m
3. Hence, the correct option is option (c) i.e 1 m.
