Question:
In the given figure, a body of mass $M$ is held between two massless springs, on a smooth inclined plane. The free ends of the springs are attached to firm supports. If each spring has spring constant $k$, the frequency of oscillation of given body is :
Correct Option: , 3
Solution:
$\mathrm{T}=2 \pi \sqrt{\frac{\mathrm{m}}{\mathrm{K}_{\mathrm{eq}}}}=2 \pi \sqrt{\frac{\mathrm{m}}{2 \mathrm{~K}}}$
$\mathrm{f}=\frac{1}{\mathrm{~T}}=\frac{1}{2 \pi} \sqrt{\frac{2 \mathrm{~K}}{\mathrm{~m}}}$
(Option 3) is correct
