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. (i) v^2=μrg (ii) μg=(v^4/r^2)+at) (iii) μ^2g^2=(v^4r^2+a^2t (iv) The force of friction makes an angle tan−1(v^2/atr) with the direction of motion at the point of slipping.

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. T1>T2 T2>T1 T1=T2 The relation between T_1 and T_2` depends on whether the rod rotates clockwise or anticlockwise.

One end of a spring of natural length h and spring constant k is fixed at the ground and the other is fitted with a smooth ring of mass m which is allowed to slide on a horizontal rod fixed at a height h. Initially, the spring makes an angle of 37° with the vertical when the system is released from rest. The speed of the ring when the spring becomes vertical is
