Question

Radha is holding a pot, filled with water, on her head and is standing at a place. Is she doing some work?

Answer 1

1. As Radha is just standing, there will no displacement by her.
2. As we know, work done is given by

$$\begin{gathered} Workdone=Forcexdisplacement \\ =ForceX0 \\ =0 \end{gathered}$$

Therefore, though she is standing with a pot filled with water, the work done will be zero.
