Q. 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) $\frac{1}{2\pi}\sqrt{\frac{K_{1}K_{2}}{m(K_{1} + K_{2})}}$
Explanation
(d) $n = \frac{1}{2\pi}\sqrt{\frac{K_{eq}}{m}} = \frac{1}{2\pi}\sqrt{\frac{K_{1}K_{2}}{(K_{1} + K_{2})m}}$
