Calculate the mass of a body whose volume is `2m^3` and relative density is 0.52.

Options

A. 104 kg
B. 1040 kg
C. 0.5 kg
D. 20 kg

Answer

B

Explanation

Density of the body,
d= relative density of the body ` xx` density of water ` = 0 . 52 xx 1000 kg// m^(3) = 520 kg// m^(3)`
Mass of the body, `M = V d = ( 2 m^(3)) xx (520 kg// m^(3)) = 1040 kg`
