A small body of mass m is attached to a light thread which passes through a hole at the centre of a smooth table. The body is set into rotation in a circle of radius r_(1) with a speed v_(1) . The thread is pulled down so that the radius of the path is changedto r_(2) . What will be the new linear speed and the new angular speed of thebody ?

1.	A small body of mass m is attached to a light thread which passes through a hole at the centre of a smooth table. The body is set into rotation in a circle of radius r_(1) with a speed v_(1) . The thread is pulled down so that the radius of the path is changedto r_(2) . What will be the new linear speed and the new angular speed of thebody ?
Answer» Answer :`[(v_(1)r_(1))/(R^(2)),omega_(1)(r_(1)/(r_(2)))^(2)]`
