According to archimedes' principle, what condition has to be met for an object to float?
a. buoyant force has to be less than the weight of the object
b. buoyant force has to equal the weight of the object
c. buoyant force has to be greater than the weight of the object
d. buoyant force has to equal exactly half the weight of the object

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".

the answer is the first option

just googled it m8. not that hard

lol

fe 55.85 g/mol and h2o 18.02 g/mol.
