A rigid ring A and a rigid thin disk B both made of same material when gently placed on water just manage to float due to surface tension as shown in the figure. Both the ring and the disk have same radius what can you conclude about their masses? (a). Both habve the same mass. (b). mass of ring is half of that of the disk (c). mass of the ring is double to that of the disk. (d). more information is needed to decide.

A ring of radius r made of wire of density ρ is rotated about a stationary vertical axis passing through its centre and perpendicular to the plane of the ring as shown in the figure. Determine the angular velocity (in rad/s) of ring at which the ring breaks. The wire breaks at tensile stress σ. Ignore gravity. Take σ/ρ = 4 and r = 1 m.
