Question

Two steel balls of radii R1 and R subscript 2 end subscript open parentheses R subscript 1 end subscript greater than R subscript 2 end subscript close parenthesesare dropped through a tube full of glycerine Their terminal velocities are v1 and v2 in the experiment, then

  1. v subscript 1 end subscript equals v subscript 2 end subscript    
  2. v subscript 1 end subscript greater than v subscript 2 end subscript    
  3. v subscript 1 end subscript less than v subscript 2 end subscript    
  4. v1 and v2 are independent of R1 and R2    

The correct answer is: v subscript 1 end subscript greater than v subscript 2 end subscript
