A man applying force of 20 N on an object at an angle of $6 0^{\circ}$ from the horizontal. If object moved by 20 m in horizontal direction, then work done by the force on the object is

Options:

Answer:

Solution:

Given, force, $f = 20 N$ , angle $θ = 6 0^{\circ}$ and displacement $(s) = 20 m$ , $∴$ Work done by the force $W = fs cos θ = 20 \times 20 \times cos 6 0^{\circ} = 20 \times 20 \times \frac{1}{2} = 200 J$
