Question

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.

Answer 1

Correct Answer - 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.
