buoyant force?

0 ⤊

The question is:

An apple floating in water displaces 50 cm^3 of water (one cm^3 of water has a mass of 1.0 grams). What is the buoyant force on this apple?

How do I work this one out. I know that d=m/v, but would this formula even apply?

The bouyant force is equal to the weight of the water displaced. Water has a mass of about 1 gram per cubic centimeter, so the bouyant force is the weight of 50 grams.

Upthrust = weight of fluid displace

W = mg
= (density)(volume)(acceleration of free fall)

W = (50E-6)(1E-3)(9.81)
