Question

A block of mass m is connected to a spring and oscillating as shown. When the block is at one of its extreme position, a wax piece of same mass m falls and sticks to the block. Match the lists.

List - I	List - II
(I) $\frac{New maximumacceleration}{Old maximum acceleration}$	(P) 1
(II) $\frac{New maximum velocity}{Old maximum velocity}$	(Q) $2$
(III) New time period	(R) $\frac{1}{2}$
(IV) New amplitude	(S) $\frac{1}{2}$
	(T) 0

At the extreme the block is momentarily at rest, so the sticking wax only doubles the mass; amplitude is unchanged.

amax = kA/m halves (I-S); vmax = Aw falls by $1/ 2$ (II-R); new T is $2$ times the old (III-Q); amplitude ratio is 1 (IV-P).
