Phase angle means a body comparing to sun in particular angle, the angle of sun changes from 0 to 180, so the angle will tends approach 180, (w/wn actual angle of abject to the natural angle of object.

Inertia force increases rapidly. Damping and spring force are reduced. So 180° is correct.

From frequency response curve. We can say that at high value of w/wn. Phase angle tends to 180°.

Frequency tans to zero.

w/wn is called frequency ratio.

W/wn means?

The correct answer is 180° based on the phase angle vs w/wn curve.
