JEE Main & Advanced Physics Fluid Mechanics, Surface Tension & Viscosity / द्रव यांत्रिकी, भूतल तनाव और चिपचिपापन Question Bank Assertion and Reason

  • question_answer
    Assertion             :       Terminal velocity is same as the critical velocity. Reason                 :       The constant velocity of fall of a body through a viscous fluid is called terminal velocity.

    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.

    E)             If assertion is false but reason is true.

    Correct Answer: E

    Solution :

                    Terminal velocity and critical velocity are not same. Critical velocity is the velocity below which the flow of liquid is streamline.
