NTA Abhyas 2022
A
The speed of the centre of mass of the cylinder is $2v$
B
The speed of the centre of mass of the cylinder is $v$
C
The angular velocity of the cylinder is $\frac{v}{R}$
D
The angular velocity of the cylinder is zero
Solution:
For no slip condition velocity of plank = velocity of bottom point of sphere.
$\omega=\frac{ v }{ R }$ and $v _{ c }=0$
