Question

if the mass of a solid body is doubled,its density is?

Answer 1

2*density if the volume is 2

Answer 2

If the mass of a solid body is doubled, its density is doubled.

Explanation:

The density of a solid body is given by mass divided by its volume. Mathematically, it is given by :

$\rho=\dfrac{m}{V}$

m is mas and V is volume

If the mass of a solid body is doubled, m' = 2m

New density becomes,

$\rho'=\dfrac{m'}{V}\\\\\rho'=\dfrac{(2m)}{V}\\\\\rho'=2\times \dfrac{m}{V}\\\\\rho'=2\times \rho$

If the mass of a solid body is doubled, its density is doubled.
