Statement I: An object from a greater height reaches a steady terminal velocity.
Statement II: The viscous forces on a body depends upon its velocity. The greater the velocity the greater is the viscous force.

A

Statement I is true, statement II is true and Statement II is a correct explanation for Statement I.

B

Statement I is true, Statement II is true and Statement II is NOT the correct explanation for Statement I.

C

Statement I is true, Statement II is false.

D

Statement I is false, Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
B
The viscous force on a body depends on its velocity. The greater the velocity, the greater its viscous force. When a body falls from a sufficient height it acquires enough velocity to produce a viscous force that balances its height. The resultant force on the body being zero, the body moves with uniform velocity called 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
