A spring having a spring constant $‘K’$ is loaded with a mass $‘m’$. The spring is cut into two equal parts and one of these is loaded again with the same mass. The new spring constant is
$\frac{K}{2}$
$K$
$2K$
${K^2}$
If a spring has time period $T$, and is cut into $n$ equal parts, then the time period of each part will be
Two pendulums have time periods $T$ and $\frac{{5T}}{4}.$They start $S.H.M.$ at the same time from the mean position. What will be the phase difference between them after the bigger pendulum has complete one oscillation ..... $^o$
Force constant of a spring is $K$ . If half part is detached then force constant of the remaining spring will be
How the period of oscillation depend on the mass of block attached to the end of spring ?
When a mass $m$ is attached to a spring it oscillates with period $4 \,s$. When an additional mass of $2 \,kg$ is attached to a spring, time period increases by $1 \,s$. The value of $m$ is ........... $kg$
