Rotational Motion question

2021 · 20 Jul · Shift 1 · Q67

JEE MainPhysicsRotational MotionNumerical+4 / −1
A circular disc reaches from top to bottom of an inclined plane of length 'L'. When it slips down the plane, it makes time 't1'. When it rolls down the plane, it takes time t2. The value of t2t1{{{t_2}} \over {{t_1}}}t1​t2​​ is 3x\sqrt {{3 \over x}}x3​​. The value of x will be ‾\underline{\hspace{2cm}}​.
