Q1:

The moment of inertia of a floating body along its longitudinal axis and the volume of water displaced by it are I and V respectively. The height of the metacentre above centre of buoyancy of the body, is

A

B

C

D

E

ANS:C -

If the metacentre is above the centre of gravity, buoyancy restores stability when the ship tilts. The stability increases with the distance between metacentre and centre of gravity called the metacentric height. If the metacentre is below the centre of gravity, the boat is unstable, and a tilt results in capsizing.
