Question

Two sphere have equal mass and volume in ratio 2:1.the ratio of their density is?

Answer 1

Answer:

Explanation:

1/2

Answer 2

Answer:

1:2

Explanation:

Density = mass/volume

1st Sphere. D1 = M/V1

D1 = M/2

2nd Sphere. D2 = M/V2

D2 = M/1

(Mass is equal)

Ratio of density = D1/D2

= M/2*1/M

Therefore ratio of density = 1:2
