Physics - NLM Question with Solution | TestHub

When a mass ' $\mathrm{m}$ ' is suspended from a spring of length ' ${\ell }^{\prime }$, the length of the spring becomes ' ${\mathrm{L}}^{\prime }$. The mass is pulled down by a distance ' $\mathrm{d}$ ' and released. If the equation of motion of the mass is $\frac{d^{2}x}{d{t}^2}+{\mathrm{P}}^{2}x=0$, then $\mathrm{P}$ is equal to $(\mathrm{g}=$ acceleration due to gravity $)$
