A ring mass 'm' and radius 'R' has three particles attached to the ring as shown in the figure the cnetre of the ring has a speed `V_(0)` . The kinetic nergy of the system in case of no slipping is -

Options

A. `6mV_(0)^(2)`
B. `12mV_(0)^(2)`
C. `4mV_(0)^(2)`
D. `8mV_(0)^(2)`

Answer

A

Explanation

`E=2/2 mV_(0)^(2)+1/2m(2V_(0))^(2)+1/2 m(sqrt(2)V_(0))^(2)+1/2 2m(sqrt(2)V_(0))^(2)`
`1/2 m(sqrt(2)V_(0))^(2)+1/22m(sqrt(2)V_(0))^(2)`
