For a particle of a rotating rigid body, `v = r omega`, which of the following are correct ?

What is KE of rotation of rigid body ?

The linear velocity of a particle on a rotating body is given by vec v = vec omega xx vec r" where "vec omega is the angular velocity and vec r is the radius vector. What is the value of |v| if vec omega = hati -2hatj+2hatk and vec r =4hatj-3hatk ?

The linear velocity of a rotating body is given by v =omega xx r , where omega is the angular velocity and r is the radius vector. The angular velocity of a body omega=hati-2hatj+2hatk and their radius vector r=4hatj-3hatk, |v| is -

Motion of the rigid body is observed from an inertial frame of reference. Rigid body is rotating with nonuniform angular speed about a fixed vertical axis. If we consider a particle of the rigid body not lying on its axis of rotation then net force acting on this particle is

Motion of the rigid body is observed from an inertial frame of reference. Rigid body is rotating with constant angular speed about a fixed vertical axis. If we consider a particle of the rigid body not lying on its axis of rotation then net force acting on this particle is.

In rotational motion of a rigid body, all particles move with
