A small particle of mass m attached with...

A small particle of mass `m` attached with a light inextensible thread of length `L` is moving in a vertical circle. In the given case particle is moving in complete vertical circle and ratio of its maximum to minimum velocity is `2:1` .
Velocity of the particle when it is moving vertically downward is

A

`(a)sqrt((10gL)/(3))`

B

`(b)2sqrt((gL)/(3))`

C

`(c)sqrt((8gL)/(3))`

D

`(d)sqrt((13gL)/(3))`

Text Solution

Verified by Experts

The correct Answer is:
A
`v=sqrt(u_(max)^(2)-2g(L))`

`=sqrt((16)/(3)-2gL)=sqrt((10gL)/(3))`
