Assertion : A balloon stops rising after attaining a certain maxium height .
Reason : Upthrust due to air decreases with height till it just balances the weight of the balloon.

A

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

B

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

C

If the assertion is true but the reason is a false statement.

D

If both assertion and reason are false statements.

Text Solution

Verified by Experts

The correct Answer is:
A
Ballon rise till the upthrust or air on it is greater than its weight . As the air becomes thinner with height at height it is reached where upthrust becomes equal to the weight of the balloon . After this stage the balloon does not rise up further .

Explain the following: A balloon filled with hydrogen rises to a certain height and then stops rising further.

A conducting bolloon of the radius a is charged to potential V_(0) and held at a large height above the earth ensures that charge distribution on the surface of the balloon remains unaffected by the presence of the earth. It is connected to the earth through a resistance R and a value in the balloon is opened . The gas inside the balloon escapes from value and the size of the balloon decreases. The rate of decrease in radius of the balloon is controlled in such a manner that potential of the balloon remains constant. Assume the electric permittivity of the surrounding air equals to that of free space (epsilon_(0)) and charge cannot leak to the surrounding air. The rate at which radius r of the balloon changes with time is best represented by the equation

Assertion : If rotation of earth about its own axis is suddenly stops then acceleration due to gravity will increase at all places on the earth. Reason : At height h from the surface of earth acceleration due to gravity is g_(h)=g(1- (2h)/R_(e)) .

These questions consists of two statements each printed as Assertion and Reason.

Assertion A block of mass m starts moving on a rough horizontal surface with a velocity v. It stops due to friction between the block and the surface after moving through a certain distance. The surface is now tilted to an angle of 30^(@) with the horizontal and the same block is made to go up on the surface with the same initial velocity v. The decrease in the mechanical energy in the second situation is smaller than that in the first situation. Reason The coefficient of friction between the block and the surface decreases with the increase in the anglle of inclination.
