Normal Forces on Sphere in Rotating Container | Circular Motion + FBD | SBT problem | JEE / NEET

The question discussed here is : A sphere of mass m and radius r = 3m is placed inside a container with flat bottom and slant sidewall as shown in the figure. The sphere touches the slant wall at point A and the floor at point B. It does not touch any other surface. The container, along with the sphere, is rotated about the central vertical axis with angular speed w. The sphere moves along with the container, i.e., it is at rest relative to the container. The normal force applied by the bottom surface and the slant
surface on the sphere are N1 and N2 respectively. There is no friction.

(a) Find the value of w above which N2 becomes
larger than N1
(b) Find the value of w above which the sphere
leaves contact with the floor.
