A vertical disc has three grooves directed along chords AB, AC and AD. Three bodies begin to slide down the respective grooves from A simultaneously. If AB > AC > AD, the respective time intervals to reach the bottoms of the respective grooves `t_1, t_2 and t_3` are 

A

`t_(1) gt t_(2) gt t_(3)`

B

`t_(1) lt t_(2) lt t_(3)`

C

`t_(1) gt t_(2) lt t_(3)`

Assertion : A ring and a disc of same mass and radius begin to roll without slipping from the top of an inclined surface at t=0 . The ring reaches the bottom of incline in time t_(1) while the disc reaches the bottom in time t_(2) , then t_(1) lt t_(2) Reason : Disc will roll down tha plane with more acceleration because of its lesser value of moment of inertia.

A particle P is sliding down a frictionless hemispherical bowl. It passes the point A at t=0 . At this instant of time, the horizontal component of its velocity is v. A bead Q of the same mass as P is ejected from A at t=0 along the horizontal string AB, with the speed v. Friction between the bead and the string may be neglected. Let t_P and t_Q be the respective times taken by P and Q to reach the point B. Then:
