MHT CET 2023 9th May Evening Shift | Simple Harmonic Motion Question 22 | Physics

A spring has a certain mass suspended from it and its period for vertical oscillations is '$$T_1$$'. The spring is now cut in to two equal halves and the same mass is suspended from one of the halves. The period of vertical oscillations is now '$$\mathrm{T}_2$$'. The ratio $$\mathrm{T}_1 / \mathrm{T}_2$$ is

$$\sqrt{2}$$

$$\frac{1}{\sqrt{2}}$$

$$\frac{1}{2}$$

$$\frac{3 \mathrm{~V}}{2}$$

$$3 \mathrm{~V}$$

$$6 \mathrm{~V}$$
