Rotational MotionHard
Question
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 : -
Options
A.remain constant
B.first decreases and then increases
C.first increases, then decrease
D.Increase continuously
Solution
As ant approaches centre, MI decreases so ω increases and then after passing centre the MI again goes increasing then angular velocity ω will become decreasing.
