Question 41

When a mass $M$ is suspended from a spring, the spring extends by an equilibrium distance $y$ . The mass is then displaced vertically and released, causing it to oscillate with a period $T$ .

The mass $M$ is removed and suspended from a different spring. This second spring extends by an equilibrium distance of $y3\frac{y}{3}$ when the same mass is suspended from it. The mass is again displaced vertically and released.

What is the new period of oscillation of $M$ in terms of $T$ ?

$T3\frac{T}{3}$

$T3\frac{T}{\sqrt{3}}$

$T3T\sqrt{3}$

$3 T$
