A wooden block sliding down from the top of a smooth inclined plane starting from rest takes t, 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°.

Options

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 _(2)`
D. `v_(1) =v_(2)` & `t_(2) = 2t_(1)`

Answer

B
