A copper ball with a volume of 50 cm3 is completely submerged in water. What is the buoyancy force on the ball?

g = 9.8 N / kg;

ρzh = 1000 kg / m³;

Vt = 50 cm³ = 50 * 0.000001 m³ = 0.00005 m³;

FA -?

The buoyancy force is calculated by the formula FA = g * ρl * Vt, where g is the acceleration of gravity (constant equal to 9.8 N / kg), ρzh is the density of the liquid (in this case, water), Vt is the volume of the ball.

Then, substituting the known values, we get:

FA = 9.8 N / kg * 1000 kg / m³ * 0.00005 m³ = 0.49 N.

Answer: the buoyancy force acting on the ball is 0.49 N.
