A stone of mass of 16 kg is attached to a string 144 m long and is whirled in a horizontal circle. The maximum tension the string can withstand is 16 Newton . The maximum velocity of revolution that can be given to the stone without breaking it, will be

A

`20m//s`

B

`16m//s`

C

`14m//s`

D

`12m//s`

Text Solution

Verified by Experts

The correct Answer is:
D
Maximum tension `=(mv^(2))/(r)=16N`
`therefore (16xxv^(2))/(144)=16 therefore v=12m//s`.
