Two discs of same moment of inertia rota...

Two discs of same moment of inertia rotating about their regular axis passing through centre and perpendicular to the plane of disc with angular velocities `omega_(1)` and `omega_(2)`. They are brought in to contanct face to face coinciding the axis of rotation. The expression for loss of energy during this process is

A

`(1)/(4)I(omega_(1)-omega_(2))^(2)`

B

`I(omega_(1)-omega_(2))^(2)`

C

`(1)/(8)I(omega_(1)-omega_(2))^(2)`

D

`(1)/(2)I(omega_(1)-omega_(2))^(2)`
