Question

a force of 10 N displaces a body by a distance of 2 m at an angle of 60^0 to its own direction , find the amount of work done.

Answer 1

Answer:

• 10 J.

Explanation:

Given: Force applied (F) = 10N

Displacement (d) = 2m

Angle between force and displacement = 60°

Work = F × S × cosФ

=> 10 × 2 × cos 60°

[ ∵ cos 60° = 1/2 ]

=> 10 × 2 × 1/2

∴ 10 J

Answer 2

Answer:10 joules

Explanation:

F=10N

S=2m

θ=60   Work=F×S×cosθ

=10×2×cos60  

=10×2× 1/2

         =10J
