MHT CET 2023 9th May Evening Shift | Simple Harmonic Motion Question 21 | Physics

Two S.H.Ms. are represented by equations $$\mathrm{y}_1=0.1 \sin \left(100 \pi \mathrm{t}+\frac{\pi}{3}\right)$$ and $$\mathrm{y}_2=0.1 \cos (100 \pi \mathrm{t})$$ The phase difference between the speeds of the two particles is

$$\frac{\pi}{3}$$

$$-\frac{\pi}{6}$$

$$+\frac{\pi}{6}$$

$$-\frac{\pi}{3}$$

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

$$\sqrt{2}$$

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

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