Solution

The correct option is C $3.9 Hz$
Given,
Force constant of spring 1 $(K_{1}) = 300 N/m$
Force constant of spring 2 $(K_{2}) = 600 N/m$
Mass of block $(m) = 1.5 kg$
Effective spring constant $(K) = K_{1} + K_{2}$
$= 900 N/m$
Frequency of oscillation $(F) = \frac{1}{2 π} \sqrt{\frac{K}{m}}$
$= \frac{1}{2 π} \sqrt{\frac{900}{1.5}}$
$= 3.9 Hz$
