sebuah batu dimasukkan kedalam wadah berisi air, hingga air tumpah sebesar 0.2 m³. jika massa jenis zat cair adalah 1,5 kg/m³ dan percepatan gravitasi 10 m/s². berapakah gaya keatas yg dialami batu?​

Hukum Archimedes

Diketahui:

  • ρ = massa jenis zat = 1.5 kg/m³
  • g = gravitasi = 10 m/s²
  • V = volume benda = 0.2 m³

Ditanya:

  • Fa = gaya angkat ?

Jawaban

Fa = ρ × g × V

Fa = 1.5 × 10 × 0.2

Fa = 15 × 0.2

Fa = 3 N ✔
