Question

Two solids A and B float in water. It is observed that A floats with half of its volume immersed Beats with 2/3 of its volume immersed. The ratio of their densities is b) 3:4 c) 2:3 d) 3:2​

Answer 1

Answer:

Correct option is

B

3 : 4

Take equal volume of A and B, say V.

Weight of A= Weight of  

2

V

​

 volume of water.

Similarly, weight of B= Weight of  

3

2V

​

 volume of water.

As density is weight per unit volume, the required ratio will be

D  

B

​

 

D  

A

​

 

​

=  

(2V/3)

(V/2)

​

=  

4

3

​

 

Thus, density of A: density of B=3:4
