An object of mass 2 kg is whirled rround in a verticle circle of radius 1m with a constant speed of `4 m//s` .Then the maximum tension in the string is `(g=10 m//s^(2))`

A

32 N

B

52 N

C

72 N

D

92 N

Text Solution

Verified by Experts

The correct Answer is:
B

`T_(max)=(mv^(2))/(r)+mg`
`=(2xx16)/(1)+2xx10=32+20`
`=52 N`
