Assume that the drag force on a football...

Assume that the drag force on a football depends only on the density of the air, velocity of the ball and the cross-sectional area of the ball. Balls of different sizes but the same density are dropped in an air column. The terminal velocity reached by balls of masses `250 g` and `125 g` are in the ratio :

A

`2^(1/6)`

B

`2^(1/3)`

C

`2^(1/2)`

D

`2^(2/3)`

A small spherical ball falling through a viscous medium of negligible density has terminal velocity v. Another ball of the same mass but of radius twice that of the earlier falling through the same viscous medium will have terminal velocity

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
