Question

The terminal velocity of a tiny brass sphere of radius r falling in a viscous liquid is vr. What will be the terminal velocity of a brass sphere of radius 2rfalling in the same liquid. 

Solution

Correct option is

 

The terminal velocity of a sphere of radius r and density  falling in a fluid of density  and viscosity  is given by 

        

. Therefore, if is double, vtbecomes 4 times.
