Question

A rubber ball floats in water with 2/7 of its volume above the surface of water calculate the relative density of rubber ball​

Answer 1

$volume \: of \: the \: rubber \: ball \: above \: the \: surface \: of \: water \: = \: 27</p><p>$

$therefore,, \:  volume \: of \: the \: rubber \: ball \: below \: the \: surface \: of \: water \: 1−27=57</p><p>$

$So,, average \: relative \: density \: of \: the \: rubber ball== Volume \: of \: the \: below \: the \: surface \: of \: water \: \\ volume \: of \: the \: ball=57×1=0.71 \\ Volume \: of \: the \: below \: the \: surface \: of \: water \: volume \: of \: the \: ball=57×1=0.71</p><p></p><p>We \: get, \: Average \: density of \: rubber \: ball \: is 0.71.</p><p></p><p>$

hope this will help you...
