Question

a coolie is walking on a railway platform with a load of 30 kg on his head how much work is done

Answer 1

HEYA

Work done is zero , because the direction of force is perpendicular to displacement

HOPE IT HELPS

PLEASE MARK S BRAINLIEST

Answer 2

Answer:

W=0

Explanation:

Coolie is carrying a load on his head so force exerted by it under gravity and displacement of the load makes 900 angle.  W = 0                                              [ ∵ Force is perpendicular to the displacement ]  

Therefore, Work done by the coolie is zero.
