Question

Potter carries load of mass 50 kg on his head and walks on a level road 100m , what is the work done by him

Answer 1

Hey mate
The work done by him is 0.
This is because work done=Force X Displacement X cosA
where A is the angle between the force and the displacement.
As in this case, angle is 90° and cos90°=0,the work done will be zero

Answer 2

● The work done will be zero because a potter carries a load make an angle of 90 degree wherever the 90 degree created the work done will be zero.

Proof:

W = FS Cos Q

W = FS Cos (90°)

W = FS (0)

W = 0
