Question

15. Give the relation between the buoyant force and the weight of a body for
a floating body.
​

Answer 1

Answer:

Explanation:

Weight of a body = mg

where, m is the mass of the body and g is the acceleration due to gravity.

In case of a floating body, the net vertical force should be zero.

And there are only 2 forces applied on the object vertically in opposite directions, i.e., the weight of the body and the buoyant force.

Therefore, the buoyant force must be equal to the weight of the body = mg
