If a small block of mass m is placed gently on M when it is passing through its mean position. Find it's new amplitude of SHM, if initial amplitude is A.
a}MM+m(A)
b}M+mM(A)
C}M+m2M (A)
d}MM−m(A)
Please read the guide .
Please answer the question in detail
Velocity at mean positon is Aω
Conserving Momentum MAω0+(M+m)V′
V′=MAωoM+m=(A′)KM+m
A′=MAKMM+m×M+mK=M(M+m)A
Hence , B option is correct
