A ball of mass is attached to the end of a string whichis being pulled through a hole on the table as shown.Initially, it is moving across the frictionless table incircular path X with a period . When the string is pulledharder, it moves inward and now moves along the circularpath Y, which has half the radius of X. Its new period is:a. 1/8T b. 1/4 T c. 1/2 T d. T e. 2T f. 4T
