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 sphere 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, then

D = 1.25 × 10^−2 m and rise of water in capillary h = 1.45 × 10^−2 m. Taking g = 9.80 m/s^2 and using the relation T = (rgh/2) × 10^3 N/m respectively. 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 The following observations were taken for dtermining the surface tension of water by capillary tube method: diameter of capillary Two spheres P and Q of equal radii have densities ρ1 and ρ2 what is the possible error in measurement of surface tension T?
