Solution

The correct option is C

According to the law of conservation of energy, elastic potential energy stored in the spring = gravitational potential energy acquired by shot

$\frac{1}{2} k x^{2} = m g h$ or $h = \frac{k x^{2}}{2 m g}$

A block of mass $m$ is attached rigidly with a light spring of force constant $k$ . The other end of the spring is fixed to a wall. If block is displaced by a distance $x$ , find the work done on the block by the spring for this range. (The spring force is given by $F = - k x$ , where $k$ is spring constant and $x$ is displacement of the block.)
