A horizontal plane supports a fixed vertical cylinder of radius R and a particle is attached to the cylinder by a horizontal thread AB as shown in the figure. The particle initially rest on horizontal plane. A horizontal velocity v 0 is imparted to the particle, normal to the threading during subsequent motion. Point out the false statements:

A disc of circumference of s is at rest at a point A on a horizontal surface when a constant horizontal force begins to act on its centre. Between A and B there is sufficient friction to prevent slipping and the surface is smooth to the right of B, AB=s. The disc moves from A to B in time T. To the right of B

A constant external torque τ acts for a very brief period Δt on a rotating system having moment of inertia I. (i) The angular momentum of the system will change by τΔt (ii) The angular velocity of the system will change by (τΔt)/I. (iii) If the system was initially at rest, it will acquire rotational kinetic energy (τΔt)2/2I. (iv) The kinetic energy of the system will change by (τΔt)2I.
