Two masses $M_{A}$ and $M_{B}$ are hung from two strings of length $l_{A}$ and $l_{B}$ respectively. They are executing SHM with frequency relation $f_{A}=2 f_{B}$, then relation
$l_{A}=4 l_{B},$ does not depend on mass
$l_{A}=\frac{l_{B}}{4},$ does not depend on mass
$l_A=2 l_B$ and $M_A=2M_B$
$l_{A}=\frac{l_{B}}{2}$ and $M_{A}=\frac{M_{B}}{2}$
A mass $M$ is suspended from a spring of negligible mass. The spring is pulled a little and then released so that the mass executes $S.H.M.$ of time period $T$. If the mass is increased by m, the time period becomes $5T/3$. Then the ratio of $m/M$ is
Two masses $m_1$ and $m_2$ are supended together by a massless spring of constant $k$. When the masses are in equilibrium, $m_1$ is removed without disturbing the system; the amplitude of vibration is
In the situation as shown in figure time period of vertical oscillation of block for small displacements will be
The frequency of oscillation of the springs shown in the figure will be
