Question

We have two different liquids A and B whose relative densities are 0.75 and 1.0, respectively. If we dip solid objects P and Q having relative densities 0.6 and 0.9 in these liquids, then:

• A. P floats in A and Q sinks in B
• B. P sinks in A and Q floats in B
• C. P floats in B and Q sinks in A
• D. P sinks in B and Q floats in A

Answer 1

The correct option is C P floats in B and Q sinks in A

If solid object has higher density than liquid then it will sink in that liquid otherwise it will float.
R.D. of liquid A = 0.75
R.D. of liquid B = 1.0
R.D. of object P = 0.6
R.D. of object Q = 0.9

• P has R.D. less then both the liquids. so it will float in both the liquids.
  
• Q has R.D. more than liquid A, so it will sink in A.
• Q has R.D. less than liquid B, so it will float in B.
