प्रश्न
A solid weighs 120 gf in air and and 105 gf when it is completely immersed in water. Calculate the relative density of solid.
उत्तर
Weight of solid in air , W1 = 120 gf
Weight of solid when completely immersed in water W2 = 105 gf
R.D. of solid = `W_1/(W_1 - W_2) xx "R.D. of water"`
R.D. of solid = `120/(120 - 105) xx 1`
R.D. of solid = 8
