MCQ

A particle, initially at rest on a frictionless horizontal surface, is acted upon by a horizontal force which is constant in size and direction. A graph is plotted between the work done $(W) $ on the particle, against the speed of the particle, $(v)$. If there are no other horizontal forces acting on the particle the graph would look like

A
B
C
✓

✓

Answer

Correct option: D.

d
(d)Work done = change in kinetic energy
$W = \frac{1}{2}m{v^2}$
$W \propto {v^2}$graph will be parabolic in nature
