The circular disc shown in its plan view in the figure rotates in a plane parallel to the horizontal plane about the point O at a uniform angular velocity w. Two other points A and B are located on the line OZ at distances and rA rB from O respectively.
The velocity of point B with respect to point A is a vector of magnitude
0
`omega` (rB - rA) and direction opposite to the direction of motion of point B
`omega` (rB - rA) and direction same as the direction of motion of point B
`omega` (rB - rA) and direction being from O to Z
