Question

A cube of density r floats in liquid A of density rho subscript 1 end subscript and partly in liquid B of density rho subscript 2 end subscript , as shown in figure. The volume of cube immersed in liquid A is less than the volume immersed in liquid B. Then

  1. rho subscript 1 end subscript less than rho less than rho subscript 2 end subscript text end textand rho greater than fraction numerator rho subscript 1 end subscript plus rho subscript 2 end subscript over denominator 2 end fraction    
  2. rho subscript 1 end subscript less than rho less than rho subscript 2 end subscript text end textand rho less than fraction numerator rho subscript 1 end subscript plus rho subscript 2 end subscript over denominator 2 end fraction    
  3. rho less than rho subscript 1 end subscript less than rho subscript 2 end subscript and rho greater than fraction numerator rho subscript 1 end subscript plus rho subscript 2 end subscript over denominator 2 end fraction    
  4. rho less than rho subscript 1 end subscript less than rho subscript 2 end subscript text end textand rho less than fraction numerator rho subscript 1 end subscript plus rho subscript 2 end subscript over denominator 2 end fraction    

The correct answer is: rho subscript 1 end subscript less than rho less than rho subscript 2 end subscript text end textand rho greater than fraction numerator rho subscript 1 end subscript plus rho subscript 2 end subscript over denominator 2 end fraction
