Find the force of gravity that acts on a copper ball with a volume of 120 cm³

univerkov | August 15, 2021 | education

V = 120 cm³ = 120 * 10 ^ -6 m ^ 3
ρm = 8.93 * 10 ^ 3 kg / m ^ 3
g = 10 m / s ^ 2
Fт -?
Fт = m * g.
m = ρm * V.
Ft = ρm * V * g.
Ft = 8.93 * 10 ^ 3 kg / m ^ 3 * 120 * 10 ^ -6 m ^ 3 * 10 m / s ^ 2 = 10.716 N
Answer: Ft = 10.716 N
