Spring Systems

A spring produces extension $'x'$ by applying a force $'F'$ N. A body of mass $'m'$ suspended from spring oscillates vertically with period $'T'$ . The mass of the suspended body is (Neglect mass of spring)

Show answer and solution

Answer: (a)

Spring constant $k = F/x$ .
$T = 2\pi\sqrt{\frac{m}{k}} = 2\pi\sqrt{\frac{mx}{F}}$
$m = \frac{T^2F}{4\pi^2x}$
So the answer is (a).
