When a liquid rotates at constant angular velocity about a vertical axis of a rigid body:
1
the pressure varies as the square of the radial distance
2
the velocity vector remains constant at a point
3
the velocity vector varies inversely as the altitude along any vertical line
4
the pressure vector varies inversely as the altitude along any vertical line
