A sample of metal weights 210 grams in air 180 grams n water and 120 grams in an unknown liquid then

A

Metal of 3

B

Metal is 7

C

Liquid of 3

D

Liquid is `(1)/(3)`

Text Solution

Verified by Experts

The correct Answer is:
B, C
Let the density of metal is p and density of liquid is `sigma`.
If V is the volume of sample then according to problem
`210 = Vrhog " "…….(i)`
`180 = V(rho-1)g " "……(ii)`
`120 = V(rho-sigma)g " "……..(iii)`
By solving (i),(ii) and (iii) we get `rho = 7` and `sigma = 3`.
