Question

A girl is standing holding her school bag in her hand. What is the work done?

Answer 1

1. We have work done $W=F.s$ where F is the force and s is the displacement.
2. Here a girl is standing holding her school bag in her hand then the work done is zero as there is no displacement.

$$\begin{gathered} W=Fs \\ W=0(\sin ces=0) \end{gathered}$$
