A small mass m attached to one end of a spring with a negligible mass and an unstretched length L, executes vertical oscillations with angular frequency omega_(0)When the mass is rotated with an angular speed omegaby holding the other end of the spring at a fixed point, the mass moves uniformly in a circular path in a horizontal plane. Then the increase in length of the spring during this rotation is

Answer»

`(OMEGA^(2)L)/(omega_(0)^(2)-omega^(2))`
`(omega_(0)^(2) L)/(omega^(2) -omega_(0)^(2))`
`(omega^(2)L)/(omega_(0)^(2))`
`(omega_(0)^(2)L)/(omega^(2))`
