Question

Unit of work in mks system is

• A. Watt
• B. Joule
• C. Calorie
• D. Newton

Answer 1

The correct option is B

Joule

Work:

1. The amount of energy transferred whenever an item is shifted across a distance by an external force, at minimum a portion of which would be applied throughout the axis of the displacement is called work.
2. Work is denoted by W.
3. The SI unit of work is $\mathrm{Joule}\left(\mathrm{J}\right)$.

Mathematically, work can be represented as:

$\mathrm{W}=\mathrm{Fs}$

Here,

W is work.

F is the force.

s is the displacement.

Therefore, option B is the correct choice.
