Two balls of equal volume and masses m1 and m2 (m2 is greater than m1) connected with a thin light thread are dropped from a certain height. Viscous drag of air on a ball depends on its velocity and buoyant force is equal to the weight of air displaced by the ball. When the balls acquire a uniform velocity after a sufficient time from the instant they were dropped, what is the tensile force in the thread ?
