Two small balls of the same size and of mass `m_(1)` and `m_(2) (m_(1) gt m_(2))` are tied by a thin weightless thread and dropped from a ballon. Determine the tension T of the thread during the flight after the motion of the balls has become steady-state.

Two small balls of the same size and of mass m_(1) and m_(2)(m_(1) gt m_(2)) are tied by a thin light thread and dropped from a large height. Determine the tension T of the thread during the flight after the motion of the balls has become steady. (Air resistance force is same on two balls) [Take m_(1)=2kg , m_(2)=1kg , g=10m//s^(2) ]

Two balls of same size but different masses m_(1) and m_(2)(m_(2)gtm_(1)) are attached to the two ends of a thin light thread and dropped from a certain height. It is known that the ciscous drag of air depends on the size and velocities of the balls. other than the gravitational pull from the earth and the viscous drag, the buoyant force from air also act on the balls, the buoyant force on a ball equals to the wweight of air displaced by the ball. After sufficiently long time from the instant the balls were dropped both of them acquire uniform velocity known as terminal velocity. When the balls have acquired terminal velocity, the tension in the thread is

Two bodies P and Q of masses m_(1) and m_(2) (m_(2) gt m_(1)) are moving with velocity v_(1) and v_(2) force exerted by P on Q during the collision is

Two masses m_(1) and m_(2) ( m_(2) gt m_(1)) are hanging vertically over frictionless pulley. The acceleration of the two masses is :

Two bodies with masses m_1 and m_2 (m_2 gt m) connected by a thread lie on a smooth table. A force Q is first applied to the larger mass and then to the smaller mass. The ratio of tensions in the thread in the two cases will be

Two blocks of masses m_(1) and m_(2)(m_(1) gt m_(2)) are connected by a massless threads, that passes over a massless smooth pulley. The pulley is suspended from the ceiling of an elevator. Now the elevator moves up with uniform velocity v_(0) Now, select the correct options:

A ball is dropped from a height of 5 m, if it rebound upto height of 1.8 m, then the ratio of velocities of the ball after and before rebound is :
