Given:-
→Force = 100N
→Distance covered = 80m
→Angle = 60°
To find:-
→Work done
Solution:-
We know that:-
=> W = F × s × cos θ
Where:-
•W is work done
•F is force
•s is distance covered
Here, θ = 60°
=> W = 100×80×cos 60°
•Value of cos θ at 60° = 0.5
=> W = 100×80×0.5
=> W = 4000 J
Thus, work done is 4000 J.
Some Extra Information:-
•Work done by a force on a body is the product of force and displacement of the body.
=> W = F×s
•Work is a scalar quantity.
•The S.I. unit of work is joule. The C.G.S. unit of work is erg.
=> 1J = 10⁷ erg.
