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 ω. Two other points A and B are located on the line OZ at distances rA and rB from O respectively
The acceleration of point B with respect to point A is a vector of magnitude
(a) 0
(b) ω(rB2 – rA2) and direction same as the direction of motion of point
(c) ω(rB – rA) and direction opposite to the direction of motion of point B
(d) ω(rB – rA) and direction being from Z to 0
