Answer:
Lets consider,
m= mass of body performing circular motion
L= angular momentum
r= radius of circular path
v= velocity of the particle
The angular momentum ,
L=mvr
v=
mr
L
. . . . . . .(1)
The centripetal force,
f
c
=
r
mv
2
. . . .(2)
Substitute equation (1) in equation (2), we get
f
c
=
r
m
(
mr
L
)
2
f
c
=
mr
3
L
2
The correct option is B.
