AIEEE 2011 | Simple Harmonic Motion Question 142 | Physics

A mass $$M,$$ attached to a horizontal spring, executes $$S.H.M.$$ with amplitude $${A_1}.$$ When the mass $$M$$ passes through its mean position then a smaller mass $$m$$ is placed over it and both of them move together with amplitude $${A_2}.$$ The ratio of $$\left( {{{{A_1}} \over {{A_2}}}} \right)$$ is :

$${{M + m} \over M}$$

$${\left( {{M \over {M + m}}} \right)^{{1 \over 2}}}$$

$${\left( {{{M + m} \over M}} \right)^{{1 \over 2}}}$$

$${M \over {M + m}}$$
