A small disc is released from rest at A on an inclined plane AB so that it rolls down wihtout slipping. It reaches the bottom with linear velocity `v_(1)` in time `t_(1)`. Next a small ring released form rest on the inclined plane AC so that it rolls down without slipping. It reaches the bottom with linear vlocity `v_(2)` in time `t_(2)`. Given `theta_(1)=30^(@), theta_(2)=60^(@),` and h=10m. Then,

A

`v_(1)gtv_(2),t_(1)ltt_(2)`

B

`v_(1)ltv_(2),t_(1)gtt_(2)`

C

`v_(1)gtv_(2),t_(1)gtt_(2)`

D

`v_(1)ltv_(2),t_(1)ltt_(2)`
