Metacentric height is given as the distance between ?








1) The center of gravity of the body and the metacenter 


2) The center of gravity of the body and the center of pressure


3) Centre of buoyancy and metacenter 


4) The center of gravity of the body and center of buoyancy





Answer: 



1) The center of gravity of the body and the metacenter 


Explanation:

The metacentric height (GM) is a measurement of the initial static stability of a floating body. It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability against overturning. The metacentric height also influences the natural period of rolling of a hull, with very large metacentric heights being associated with shorter periods of roll which are uncomfortable for passengers. Hence, a sufficiently high but not excessively high metacentric height is considered ideal for passenger ships.
