Question

Determine the amount of work done when an object is displaced at an angle of 30 degree with respect to the direction of the applied force.

Answer 1

Work done on a body when the body moves at an angle to the direction  of force applied.W=Fx d cosθwhere F is forced is displace,and θ is the angle between  F and d.

Given that θ is 30°
Workdone =W=Fxd Cos30°
=Fxd √3/2

Answer 2

Given,
Angle between f and d ($\theta$) = 30°

We know,
Work done = F × d cos$\theta$
= F × d cos30°
= F × d $\sqrt{\frac{3}{2}}$
