A $\displaystyle 1$ kg block attached to a spring vibrates with a frequency of $\displaystyle 1$ Hz on a frictionless horizontal table. Two springs identical to the original spring are attached in parallel to an $\displaystyle 8$ kg block placed on the same table. So, the frequency of vibration of the $\displaystyle 8$ kg block is :
Official answer
(3)
$\displaystyle \frac{1}{2} \mathrm{~Hz}$
