Physics - Elasticity Question with Solution | TestHub

$\mathrm{ABCD}$ is an elastic string of natural length 3 m and particles of equal mass are attached to the unstretched string at points B and C where $\mathrm{AB}=\mathrm{BC}=\mathrm{CD}$. The ends A and D are then attached to two points on the same horizontal level and 3 m apart. The particles hang in equilibrium so that the string sections AB and CD are each at $60^0$ to the horizontal. Force constant of the string is $50\mathrm{N}/\mathrm{m}$.
