Two discs of moment of inertia I(1) and...

Two discs of moment of inertia `I_(1)` and `I_(2)` about their respectively axes (normal) to the disc and passing through the centre) , and rotating with angular speed `omega_(1)` and `omega_(2)` are brought into contact face to face with their axes of rotation coincident .
What is the loss in kinetic energy of the system in the process ?

A

`(I_(1) I_(2) (omega_(1) - omega_(2))^(2))/(2 (I_(1) + I_(2)))`

B

`(I_(1) I_(2) (omega_(1) - omega_2)^(2))/((I_(1) + I_(2)))`

C

`(I_(1) I_(2) (omega_(1) + omega_(2))^(2))/((I_(1) - I_(2)))`

D

`(I_(1) I_(2) (omega_(1) + omega_(2))^(2))/(2 (I_(1) - I_(2)))`
