A body moves on a horizontal circular road of radius r, with a tangential acceleration at. The coefficient of friction between the body and the road surface Is μ. It begins to slip when its speed is v.

A rod of length L is pivoted at one end and is rotated with as uniform angular velocity in a horizontal plane. Let T1 and T2 be the tensions at the points L/4 and 3L/4 away from the pivoted ends. 1. T1>T2 2. T2>T1 3. T1=T2 4. The relation between T_1 and T_2` depends on whether the rod rotates clockwise or anticlockwise.
