A body of weight `27N` hangs on a long spring of such stiffness that an extra force of `9 N` stretches the spring by `0.05m`. If the body is pulled downward and released, what is the period ?

Explanation

To solve the problem step by step, we will follow these key points:

### Step 1: Determine the Spring Constant (k)
Given that an extra force of \( F = 9 \, \text{N} \) stretches the spring by \( x = 0.05 \, \text{m} \), we can use Hooke's Law, which states:

\[ F = kx \]
