Question

A coolie carries a load of 50 kg on his head and walk on a label road Upto 100 metre. what is the work done by him​

Answer 1

Answer: Work done is 0 because since it is perpendicular to the ground and cos90 degree is 0

Answer 2

$\huge\star\mathfrak\red{{Hey Mate...!!}}$

● The work done will be zero because a coolie 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
