A large drum having radius $R$ is spinning around its axis with angular velocity $\omega$ , as shown in figure. The minimum value of $\omega$ so that a body of mass $M$ remains stuck to the inner wall of the drum, taking the coefficient of friction between the drum surface and mass $M$ as $\mu$ , is :

A vertical cylindrical drum of radius R rotates about its central vertical axis with angular velocity omega, and a block of mass M is shown pressed against the inner wall.

A
$\sqrt{\frac{\mu g}{R}}$
B
$\sqrt{\frac{g}{\mu R}}$
C
$\sqrt{\frac{2g}{\mu R}}$
D
$\sqrt{\frac{g}{2\mu R}}$
