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

An oil drop of mass m fall through air with a terminal velocity in the presence of upward electric field of intensity E . the drop carries a charge +q . R is the viscous drag force and f is the buoyancy force . Them for the motion of the drop.

A car having cross sectional area of its front equal to A is travelling on a highway at a speed v. The viscous drag force acting on the car is known to be given as F_(v)=CArhov^(2) .Where rho is density of air and C is a constant which depends on the shape of the car. The petrol used by the car produces E joules of energy per kg of it burnt. Calculate the mileage (in km/kg) of the car if the combined efficiency of its engine and transmission is f.
