A) directly proportional to\[\sqrt{m}\]
B) directly proportional to m
C) independent of m
D) directly proportional to \[\frac{1}{\sqrt{m}}\]
Correct Answer: C
Solution :
According to work energy theorem, change in kinetic energy \[=F\times S\] Since, \[F\] and \[S\] are constant, the kinetic energy gained does not depend upon the mass of the particle. Note that, in question No. 55, kinetic energy is different for particles of different masses as they are acted upon by different forces\[(mg)\].
