The frequency of oscillation of the springs shown in the figure will be

A

$\frac{1}{{2\pi }}\sqrt {\frac{K}{m}} $

B

$\frac{1}{{2\pi }}\sqrt {\frac{{({K_1} + {K_2})m}}{{{K_1}{K_2}}}} $

C

$2\pi \sqrt {\frac{K}{m}} $

D

$\frac{1}{{2\pi }}\sqrt {\frac{{{K_1}{K_2}}}{{m({K_1} + {K_2})}}} $

(AIIMS-2001)

Solution

(d)$n = \frac{1}{{2\pi }}\sqrt {\frac{{{k_{eq}}}}{m}} = \frac{1}{{2\pi }}\sqrt {\frac{{{k_1}{k_2}}}{{({k_1} + {k_2})m}}} $
