One-forth length of a spring of force constant $K$ is cut away. The force constant of the remaining spring will be
$\frac{3}{4}K$
$\frac{4}{3}K$
$K$
$4 K$
The vertical extension in a light spring by a weight of $1\, kg$ suspended from the wire is $9.8\, cm$. The period of oscillation
A mass $m$ is suspended by means of two coiled spring which have the same length in unstretched condition as in figure. Their force constant are $k_1$ and $k_2$ respectively. When set into vertical vibrations, the period will be
In the situation as shown in figure time period of vertical oscillation of block for small displacements will be
The frequency of oscillation of a mass $m$ suspended by a spring is $'v'$. If mass is cut to one fourth then what will be the frequency of oscillation ?
If a spring has time period $T$, and is cut into $n$ equal parts, then the time period of each part will be
