Question

Mechanically work done is equal to (symbols have their usual meanings)

• A. $W=F/d$
• B. $W=Fd$
• C. $W=F+d$
• D. $W=F-d$

Answer 1

The correct option is B

$W=Fd$

1. Work is done by a force on a body when it displaces the body through a certain distance.
2. Work done $W$ is the product of the force applied $F$ and displacement $d$ of the body.
3. Mathematically, $W=F\times d$

Thus, $W=Fd$ is the correct representation of work.

Hence, option (b) is correct.
