The K.E (K ) of a particle moving along a circle r depends upon the distance covered (s) as ` K= as ^(2)` The centripetal force acting on the particle is given by

A

`2as`

B

`2as^(2)`

C

`(2as^2)/(r )`

D

`(2 ar )/( s^2)`

Text Solution

Verified by Experts

The correct Answer is:
C
K.E `=(1)/(2) mv^(2) = as^(2)`
C.P force `(F ) =(mv^2)/(r ) =(2((1)/(2)mv^2))/(r ) =(2as ^(2))/(r )`
