A disc is rotating with constant angular velocity about an axis passing through centre \( \mathrm{C} \) and perpendicular to the plane of disc. An insect is moving over the disc along radial direction with constant velocity with respect to the disc. Acceleration of the insect at the instant when its distance from centre is \( r \), will be:
(1) \( r \omega^{2} \) towards the centre
(2) \( r \omega^{2} \) away from the centre
(3) Less than \( r \omega^{2} \) in magnitude
(4) Greater than \( r \omega^{2} \) in magnitude
\( \mathrm{P} \)
W
