Two spheres P and Q of equal radii have densities 
and 
, respectively. The spheres are connected by a massless string and placed in liquids L 1 and L 2 of densities 
and 
and viscosities 
and 
, respectively. They float in equilibrium with the sphere P in L 1 and sphere Q in L 2 and the string being taut (see figure). If sphere P alone in L 2 has terminal velocity 
and Q alone in L 1 has terminal velocity 
, then
L2
