The clock is pulling the force towards earth's center because of gravity.

That force is equal to:

F = m*g where g is gravitational acceleration.

We will take that g = 9.81m/s^2

Now:

F = 0.25 * 9.81 = 2.4525 N

The string needs to sustain that force, therefore minimum Force that string has to be able to sustain is:

2.4525 N
