Question

A solid object of mass 5 kg floats in a liquid . Calculate the buoyant force acting on the body.

Answer 1

A body floats only when the upward thrust is equal to the weight of the body.

In short, body weight mg= buoyant force of the liquid.

Weight of the object in the above problem =5*9.8 = 49N

Therefore, if the body has to float on water the upward force should be not less than 49N.

Answer 2

Answer:

Explanation:

A body floats only when the upward thrust is equal to the weight of the body.

In short, body weight mg= buoyant force of the liquid.

Weight of the object in the above problem =5*9.8 = 49N

Therefore, if the body has to float on water the upward force should be not less than 49N.
