Statement I: A raindrop after failing through some height attains a constant velocity.
Statement II: At constant velocity, the viscous drag is just equal to its weight.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
When a body falls through a viscous medium, finally, it attains terminal velocity. At this velocity, viscous force on rain drop balances the weight of the body.

Statement -1 : A rain drop after fallling through some height attains a constant velocity. Statement -2 : At constant velocity, the viscous drag is just to its weight.

Statement -1 : All the raindrops hit the surface of the earth with the same constant velocity. Statement -2 : An object falling through a viscous medium eventually attains a teerminal velocity.

Some question (Assertion-Reason type) are given below. Each question contains STATEMENT-1(Assertion) and STATEMENT-2(Reason) . Each question has 4 choices (A),(B),(C ) and (D) out of which ONLY ONE is correct. So select the correct choice : STATEMENT-1 A rain drop after falling through a certain distance attains a constant velocity. STATEMENT-2 The viscous force for spherical body is proportional to its speed. Hence after falling through a certain distance viscous drag and buoyant forces balance the gravitational force.

Statement - I : Electric lines are always straight and continuous. Statement - II : Electric lines represents velocity field.

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.

Statement - 1: A particle moves along a straight line with constant velocity. Now a constant non-zero force is applied on the particle in direction opposite to its initial velocity. After the force is applied, the net work done by this force may be zero in certain time intervals. Statement - 2 : The work done by a force acting on a particle is zero in any time interval if the force is always perpendicular to velocity of the particle.

Statement I: A hydrogen-filled balloon stops rising after it has attained a certain height in the sky. Statement II: The atmospheric pressure decreases with height and becomes zero when the maximum height is attained.

Statement I: The average velocity of the body may be equal to its instantaneous velocity. Statement II: For a given time interval of a given motion, average veocity is single valued while average speed can have many values.
