Answer is (A)
P.E of the oscillating mass is given by
When only black is oscillating, at
and at mean position i.e.
When mass is placed on top of the mass
Then, total mass is and at this point, as .
When the combination reaches ,
Then
A mass ‘ ‘ connected to a horizontal spring performs S.H.M. with amplitude ‘‘. While mass ‘ ‘ is passing through mean position another mass ‘ ‘ is placed on it so that both the masses move together with amplitude , The ratio of is
