Answer 2

Hello mate

Here,

volume of sphere = Volume of water displaced = 2.2 × 104 m3

(∠sphere is completely immersed in water)

Mass of the water displaced = Volume × Density = 2.2 × 104m3 × 1000 kg m3 = 2.2 × 101 kg

Thus,

buoyant force exerted by water = weight of water displaced = mg= 2.2 × 101 kg × 9.8 m/s2 = 21.56 × 101 N = 2.156 N
