Question

Q7) Relative density of liquid A is 3.5 and that of liquid B is
1.7. A body with relative density 2.2 is immersed in both the
liquids. Explain whether the lady will float or sink?
​

Answer 1

Answer:

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.
