Question

A metal sphere of volume V having a cavity inside it floats on water completely submerged if the relative density of metal is 1.5,volume of cavity is______.

Answer 1

Answer:

Explanation:

Hi ,let the volume of cavity be v

Total volume of metal = V - v

But total volume submerged = V

Thus volume of water displaced = V

As relative density of metal is 1.5

then V-v * 1.5 = V * 1

Or 1.5 V - 1.5 v = V

==> 0.5 V = 1.5 v

OR v = 1/3 V
