is the centre of disc and 
is a point on disc as shown in Figure. In each situation oc column I a statement is given and the corresponding results are given in Column II. Match the statements in Column I with the results in Column II

(b)
a. Speed of point 
change with time
b. Acceleration of point 
is equal to 
angular speed of disc and 
. The acceleration is direction from 
towards 
c. The angle between acceleration of 
(constant in magnitude) and velocity of 
changes with time. Therefore, tangential acceleration of 
changes with time
d. The acceleration of the lowest point is directed towards the centre of the disc and remains constant with time
