MCQ

A body, acted upon by a force of $50 \,N$ is displaced through a distance $10$ meter in a direction making an angle of $60^°$ with the force. The work done by the force be ..........$J$

A
$200$
B
$100$
C
$300$
✓
$250$

✓

Answer

Correct option: D.

$250$

d
(d) $W = \overrightarrow F \,.\,\overrightarrow S = FS\cos \theta $

$ = 50 \times 10 \times \cos 60^\circ = 50 \times 10 \times \frac{1}{2} = 250\,J.$
