Question

A small ball of mass M is attached to two identical springs of constant k, which are attached to floor and roof. The springs have unstretched length l/2. At what distance from the ceiling ball remain at equilibrium?

$\frac{1}{2} l (1 + \frac{M g}{k l})$
$\frac{l}{3} (1 + \frac{2 M g}{k l})$
$\frac{l}{4} (1 + \frac{M g}{2 k l})$
$\frac{2 l}{3} (1 + \frac{M g}{4 k l})$

The correct answer is: $fraction numerator l over denominator 3 end fraction open parentheses 1 plus fraction numerator 2 M g over denominator k l end fraction close parentheses$
