Two spheres P and Q of equal radii have densities ρ1 and ρ2 repectively. The spheres are connected by a massless string and placed in liquids L1 and L2 of densities σ1 and σ2 and viscosities η1 and η2 respectively. They float in equilibrium with the sphere P in L1 and Q in L2 and the string being taut (see figure). If sphere P alone in L2 has terminal velocity →VP and Q alone in L1 has terminal velocity →VQ, (Terminal velocity of a sphere having radius r and density ρ thrown in a liquid having density σ and viscoscity η is given by =2r29η(ρ−σ)). Then which of the following are correct ? |
