Question

Determine the work done when an object is displaced at an angle of 30°with respect to the direction of the aoplied force

Answer 1

Hey mate here is ur solution..

______________

let F be the force & ∆=30° be the angle between displacement which is 's'

Work done= F.S
=|F| |S| Cos ∆
= |F| |S| Cos30°

=| F| |S|√3/2

where | F| be magnitude of force
| S| be magnitude of displacement
