Spring Systems

A mass is suspended separately by two different springs in (successive order then time periods is t1 and t2 respectively, If it is connected by both spring as shown in figure then time period is t0, the correct relation is

Show answer and solution

Answer: (b)

The figure shows the springs in parallel: $k_0 = k_1 + k_2$ .
$k \propto t^{-2}$ , so $t_0^{-2} = t_1^{-2} + t_2^{-2}$ .
So the answer is (b).
