Question

A force of 20n displace a body thrown a distance of 1 m at an angle of 60 digree

Answer 1

A force of 20 N displaces a body through a distance of 1 mat an angle of 60° from its own direction. Calculate the amount of work done.

Here, force F = 20 N, displacement, s = 1 m.

Angle between force and displacement 0 60°.

Workdone,W =Fscos0 =20 X 1 X cos60°=20X 1 X 1/2 = 10J.
