Q. An ant is sitting at the edge of a rotating disc. If the ant reaches the other end, after moving along the diameter, the angular velocity of the disc will:-

Remain constant

First decreases and then increases

First increases, then decrease

Increase continuously

Initially as ant move towards axis $I$ decreases so $ω$ increases
After crossing axis $I$ increases and $ω$ decreases
so, first $ω$ increases then $ω$ decreases
