When a mass $m$ is attached to a spring, it normally extends by $0.2\, m$. The mass $m$ is given a slight addition extension and released, then its time period will be
$\frac{1}{7}\, sec$
$1\, sec$
$\frac{{2\pi }}{7}\,sec$
$\frac{2}{{3\pi }}\,sec$
Show that the oscillations due to a spring are simple harmonic oscillations and obtain the expression of periodic time.
The spring mass system oscillating horizontally. What will be the effect on the time period if the spring is made to oscillate vertically ?
If a watch with a wound spring is taken on to the moon, it
The springs shown are identical. When $A = 4kg$, the elongation of spring is $1\, cm$. If $B = 6\,kg$, the elongation produced by it is ..... $ cm$
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
