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 : [21 Jan 2026 Shift 2]
