How is the metacentric expressed? height, GM
a. GM = BG-(I/V)
b. GM = (V/I)- BG
c. GM = U/V)-BG
d. GM = BG- (V/I)
where I = Moment of inertia of the plan of the floating body at the water surface V = Volume of the body submerged in water BG = Distance between the centre of gravity (G) and the centre of buoyancy (B).
