Question

A body is acted upon by a force which is proportional to the distance covered. If distance covered is represented by s, then work done by the force will be proportional to.

• A. s
• B. $s^2$
• C. $\sqrt{s}$
• D. None of the above

Answer 1

The correct option is B $s^2$

Given that-

$F\propto s$

$⟹F=ks$ where $k=$ proportionality constant

Now, we know that, Work done $W=F.s$

$⟹W=k{s}^2$

$⟹F\propto s^2$

Answer-(B)
