Question

Question :  A mass suspended on a frictional less horizontal surface. It is attached to a string and rotates about a fixed centre at an angular velocity w0. If length of the string and angular velocity are doubled the tension in the string which was initially T0 is now

Answer 1

To=mw²l

Now length and w are doubled

T=8mw²l

To/T =1/8

To=T/8
