1.

is totn iron ball of density 7.8 g/cm3 andupthrust on it.m3 andvolume 200 cm3 is totally immersed in water. Calculate the2bween the incident ray

Answer»

When a body is immersed in a liquid, the upthrust isF =ρvg

here;liquid is water, soρ=1000 kg/m³volume, v = 200 cm³ = 200×10⁻⁶ m³g = 9.8 m/s²

Upthrust, F =ρvg = 10³× (200×10⁻⁶)× 9.8 = 1.96N
