Question

an insect moves along a diameter of a revolving round table which is rotating at a uniform rate of p radians per second .Assuming that the insect has a constant speed V relative to the table find its acceleration as it passes through the centre of the table.​

Answer 1

Explanation:

As external torque is zero, i.e.

, so angular momentum is conserved. <br>

constant

<br> or

<br> When insect moves towards centre

decrease. Hence

increases. As insect moves away from centre towards diametrically opposite point,

increases. Then

decreases. Thus

first increases and then decrease.
