A wooden block sliding down from the top...

A wooden block sliding down from the top of a smooth inclined plane starting from rest takes `t_(1)`, seconds to reach the bottom of the plane and attains velocity `V_(1)`. Another block of twice the mass falling freely from the same height takes `t_(2)` sec. to reach the bottom of the plane and attains `V_(2)`. If angle of inclination of the plane is `30^(@)`.

A

`v_(1) =v_(2)` & `t_(1) =t_(2)`

B

`v_(1) =v_(2)` &`t_(1) = 2t_(2)`

C

`v_(1) gt v_(2)` & `t_(1) gt t_(2)`

D

`v_(1) =v_(2)` & `t_(2) = 2t_(1)`
