Then particle will pull the string (with it's own weight too) towards the ground.

Step-by-step explanation:

As we know that the force of gravity is pulling that string towards the ground.

          The force of gravity = acceleration of gravity x mass of particle and the string,

    Take them as,

                                    ⇒ F = m x g

Where 'm' is the mass of particle and string.

From Hooke's law, the force needed to extend the string is given by,

                                   ⇒ F = k\times x

   where, 'k' is the spring constant and 'x' is the deflection of spring (extension).

So,

                                   ⇒  k\times x = m x g

                                   ⇒ k = \frac{m \times g}{x}
