Question

Consider the following statements:
S₁ : Zero net torque on a body means always absence of rotational motion of the body.
S₂: A particle may have angular momentum even though the particle is not moving in a circle.
S₃: A ring of rolling without sliding on a fixed surface. the centripetal acceleration of each particle with respect to the centre of the ring is same.
State in order, whether $s subscript 1 comma s subscript 2 comma s subscript 3$ are true or false.

FTT
FFT
TTF
FTF

The correct answer is: FTF

In case of pure rolling, torque due to friction about contact is zero.

An equilateral triangle ABC formed a uniform wire has two small identical beads initially located at A. The triangle is set rotating about the vertical axis AO. Then the beads are released from rest simultaneously and allowed to slide down, one along Ab and other AC as shown. Neglecting frictional effects, the quantities that are conserved as beads slides down are:
