PhysicsEasysingle choice

A block of mass ' $m$ ' attached to one end of the vertical spring produces extension $x^{'}$ . If the block is pulled and released, the periodic time of oscillation is

Options:

Answer:

Solution:

(A) $mg = - kx ∴ k = \frac{mg}{x}$ $ω^{2} = \frac{k}{m}$ $(\frac{2 π}{T})^{2} = \frac{k}{m}$ $\frac{4 π ^{2}}{T ^{2}} = \frac{k}{m}$ $∴ T^{2} = \frac{4 π ^{2} m}{k} = \frac{4 π ^{2} m x}{m g} \Rightarrow T = 2 π \frac{x}{g}$
