A particle of mass $$m$$ is revolving in a horizontal circle on a frictionless horizontal table with the help of a string tied to it and passing through a hole at the center of the table. Two equal masses $$M$$ are attached to the other end of the string as shown. If one of the hanging masses $$M$$ is removed gently, the radius of the circular motion of $$m$$

A

decreases by a factor $$1.414$$

B

increases by a factor $$1.260$$

C

increases by a factor $$1.414$$

D

does not change because of the conservation of angular momentum
