An ideal spring supports a disc of mass M. A body of mass m is released from a certain height from where it falls to hit M. The two masses stick together at the moment they touch and move together from then on. The oscillations reach to a height a above the original level of the disc and depth b below it. The constant of the force of the spring is

1.	An ideal spring supports a disc of mass M. A body of mass m is released from a certain height from where it falls to hit M. The two masses stick together at the moment they touch and move together from then on. The oscillations reach to a height a above the original level of the disc and depth b below it. The constant of the force of the spring is
Answer» `(2MG)/(b-a)` `(MG)/(b-a)` `(2mg)/(a-b)` `(mg)/(2(a-b))` ANSWER :C
