If B = centre of buoyancy, G = centre of gravity, B1 = new centre of buoyancy when the floating body rotates by an angle θ, then the location of metacentre will be:
If B = centre of buoyancy, G = centre of gravity, B1 = new centre of buoyancy when the floating body rotates by an angle θ, then the location of metacentre will be: Correct Answer at the point of intersection of axis of floating body passing through B and G and vertical line passing through B<sub>1</sub>
Concept:
The point ' M ' at which the line of action of the new buoyant force intersects the original vertical through the CG of the body, is called the meta-centre. It is a point about which a floating body starts oscillating when given a small angular displacement.
