A small disc is released from rest at A on an inclined plane AB so that it rolls down without 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,

Options

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)`

Answer

C
