Question

In case of floating body, the location of centre of gravity relative to metacentre determines the angular stability of the body due to
a. The centre of buoyancy changes with the angular displacement of the floating body
b. Lower volume of displaced water
c. Distance between centre of gravity and centre of bouncy is very high
d. None of the above​

Answer 1

correct option will be (a)

Answer 2

option (a) is correct

a. The center of buoyancy changes with the angular displacement of the floating body.

Explanation : The outcome of the buoyancy forces acts on an immersed body through the center of buoyancy. If the body is entirely immersed, it coincides with the liquid's center of gravity, which is shifted.

The center of buoyancy of a floating body is at the center of gravity of the immersed part of the floating body in the liquid, and it is vertically below the center of gravity of the entire body.
