A body whose mass is 2kg and has a volume of 500cm3 just floats when completely immersed in a liquid. Calculate the density of the liquid

A.

4.0 x 102kgm-3

B.

4.0 x 103kgm-3

C.

1.0 x 103kgm-3

D.

1.0 x 106kgm-3

Correct answer is B

since the object floats, density of liquid = density of object

converting 500cm3 to m3,

500106=5×104m3

D = mv

= 25×104

=4.0×103kgm3
