A thin horizontal circular disc is rotating about a vertical axis passing through its centre. An insect is at rest at a point near
\( \mathrm{P} \) the rim of the disc. The insect now moves along a diameter
W of the disc to reach its other end. During the journey of the insect, the angular speed of the disc
(1) remains unchanged
(2) continuously decreases
(3) continuously increases
