Question

A girl standing on one leg during an exercise does a lot of work.

• A. True
• B. False

Answer 1

The correct option is B False

1. A girl standing on one leg during an exercise means displacement is zero hence no work is said to be done.
2. $\mathrm{Work}\left(\mathrm{W}\right)=\mathrm{F}.\mathrm{ds}=\mathrm{F}\times 0=0$

Hence given statement is false.
