Question

the mass of a body is 70 kg when completely immersed in water it displaced 2000 cm cubic of water what is the relative density of the material of the body

Answer 1

volume= 2000 cm3
or 2000 x 10⁻⁶ m₃ or 2 x 10⁻³ m₃

density= 70 kg / 2 x 10 ⁻³
= 5 x 10 ³

relative denisty= denisty of substance/ water density
= 35 x 10³ / 10³
=35

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!! :)
