Question

The mass of a body is 70 kg when completely immersed in water it displaces 2000cm3 of water. find the relative density of the body

Answer 1

Answer is 25g/cc
Mass is 70kg
Mass of water displaced is v *d
2000cc*1 is equal to 2000gram
Is equal to 20kg
Apparent weight in water is equal to 70kg -20kg is 50 kg
Since volume of body is equal to volume of water displaced is equal to 2000cc
Density of body is m/v is 50000g/2000cc
Is 25 gm/cc
Since density is numerically equal to relative density so RD of solid is 25

Answer 2

$\textbf{\huge{ANSWER:}}$

Given:
Mass = 70 kg
Weight of water displaced = 2000${cm}^{3}$

Weight = 2000${cm}^{3}$

=》 2×${10}^{-3} {cm}^{3}$

Density of the substance = $\frac{70}{2 \times {10}^{-3}}$

=》 $35 \times{10}^{3}$

Relative Density = $\frac{Density\:of\:substance}{Density\:of\:water}$

=》 $\frac{35 \times{10}^{3}}{{10}^{3}}$

=》 $\textbf{35}$

Hope it Helps!! :)
