A metallic sphere of mass 1 kg and volume 2 \times 10^{-4}~m^{3} is completely immersed in water. The buoyant force exerted by water on the sphere is: (Given: density of water = 1000 kg/m^{3}, g = 10~m/s^{2})
- A. 0.5 N
- B. 1.5 N
- C. 2 N ✓
- D. 2.5 N
Correct Answer: C. 2 N
Explanation
Buoyant force F_{b} = \rho Vg = 1000 \times (2 \times 10^{-4}) \times 10 = 2 N.
