A body weighs $2.85 \mathrm {~N}$ in air and $2.35 \mathrm {~N}$ when completely immersed in water. Determine (a) the volume of the body, (b) the density of the body, and (c) the relative density of the body. Take density of water as $1000 \mathrm {~kg} / \mathrm { m } ^ { 3 }$ and gravitational acceleration, g, as $9.81 \mathrm {~m} / \mathrm { s } ^ { 2 }$
