372101 A small object placed on a rotating horizontal turn table just slips when it is placed at a distance \(9 \mathrm{~cm}\) from the axis of rotation. If the angular velocity of the turn table is tripled the object slips when its distance from the axis of rotation is :
372102 An insect crawls up a hemispherical surface very slowly. The coefficient of friction between the insect and the surface is \(1 / 3\). If the line joining the centre of hemispherical surface and the insect makes an angle \(\alpha\) with the vertical, what is the maximum value of \(\alpha\) ?
