Which of the following statement is/are INCORRECT about a solid sphere rotating about a fixed axis passing through its center, with constant angular velocity ? Consider r<R, where R is radius of sphere.

All points in sphere at perpendicular distance ‘r’ from the axis same velocity

The magnitude of acceleration of all points in sphere at perpendicular distance r from the axis is same

No two points on the sphere can have same acceleration

All points on the surface of the sphere have same speed.
