1.	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^(@).
Answer» `v_(1)=v_(2)` & `t_(1)=t_(2)` `v_(1)=v_(2)` & `t_(1)=2t_(2)` `v_(1)GT v_(2)` & `t_(1)gt t_(2)` `v_(1)=v_(2)` & `t_(2)=2t_(1)` Answer :B
