Given that,
Distance moved by the box, d = 10 m
Force applies, F = 20 N
It is applied at an angle of 30 degrees.
To find,
The work done on the box by the force F during the displacement.
Solution,
The work done by an object is given by the formula as follows :
[tex]W=Fd\cos\theta\\\\W=20\times 10\cos(30)\\\\W=173.20\ J[/tex]
So, the required work done on the box by the force is 173.20 J.
