Question

A body of wood has weight w and volume v the apparent weight of this body after making it float onwater will be

Answer 1

Explanation:

• The actual weight doesn’t change. The water applies and upward force equal to the weight of the object (or it sinks).
• Conceptually, because the upward force equals the downward force, the object is weightless.
• Don’t tell that, however, to an other item in the water that gets squashed in a collision with the buoyant object.

So apparent weight (up-down) is zero; but apparent weight (left-right) hasn’t changed.
