Given
Force (F) = 20 N
Displacement (s) = 1 m
Angle between force and displacement θ = 60°
★ Work (W) = Fs cos θ
= 20 × 1 × cos 60°
= 20 × 1 × ½
= 10 J

☢️ hi mate........
☢️answer......
☢️cos 60= 0.5
☢️Force= 20N
☢️Distance= 1m
☢️Work done = F*cos tetha*distance
= 20*0.5*1
=20*5/10*1
=10*1=10
Therefore the work done=10J
