Kinematics Question 254
Question: A body, acted upon by a force of 50 N it’s d it’splaced through a distance 10 meter in a direction making an angle of 60° with the force. The work done by the force be
Options:
A) 200 J
B) 100 J
C) 300
D) 250 J
Correct Answer: D $ W=\overrightarrow{F}.\overrightarrow{S}=FS\cos \theta $ $ =50\times 10\times \cos 60{}^\circ =50\times 10\times \frac{1}{2}=250J. $Show Answer
