Question

According to Archimedes' Principle, what condition has to be met for an object to float?

Answer 1

C. The buoyant force must be greater to float, otherwise it would sink, its like a barrel in water, the more water weight in it the more it sinks, the more air weight the more it rises.

Answer 2

Answer:

Buoyant force has to be greater than the weight of the object

Explanation:

According to Archimedes principle, the upward buoyant force is equal to the weight of the liquid displaced if an object is fully or partially immersed in a liquid. When an object is immersed in water, two forces act on it :

1. Buoyant force or upthrust, an upward force, which opposes the weight of an object inside water.          

2. Gravitational force, which act in downward direction always.

The floating or sinking of an object depend on the amount of buoyant force. If the buoyant force is greater than the weight of the object, it will float and if the buoyant force is less than the weight of the object, it will sink in liquid.

Hence, the correct option is (c) " buoyant force has to be greater than the weight of the object".
