When a body floating in a liquid, is displaced slightly, it oscillates about A. e.g. of body B. center of pressure C. center of buoyancy D. metacentre

[amp_mcq option1=”e.g. of body” option2=”center of pressure” option3=”center of buoyancy” option4=”metacentre” correct=”option4″]

The correct answer is D. metacentre.

The metacentre is a point in a floating object where the upward force of buoyancy and the downward force of gravity are in balance. When a floating object is displaced slightly, it will oscillate about the metacentre.

The center of buoyancy is the point where the upward force of buoyancy acts on a floating object. The center of pressure is the point where the downward force of gravity acts on a floating object. The e.g. of body is not a relevant concept in this context.
