If a body of mass 500 gm is revolving in a horizontal circle od radius 0.49 m , then the centripetal force acting on it (if its period is 11 s ), will be

A

0.008N

B

8.0 N

C

0.8N

D

0.08 N

Text Solution

Verified by Experts

The correct Answer is:
D
`F=m r omega^(2)=mr(4pi^(2))/(T^(2))`
`=(0.5xx0.49xx4xx(22)/(7)xx(22)/(7))/(11xx11)=0.08`.
