A particle at rest on a frictionless table is acted upon by a horizontal force which is constant in magnitude and direction. A graph is plotted of the work done on the particle W, against the speed of the particle v. If there are no frictional forces acting on the particle, the graph will look like

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Form work-energy theorem
W=change in kinetic energy
or`" " W=(1)/(2)mv^(2)`
`:.` W-v graph is a parabola.
