JEE Main & Advanced Physics Vectors Question Bank Assertion and Reason

  • question_answer
    Assertion             :               Multiplying any vector by an scalar is a meaningful operations.                 Reason                 :               In uniform motion speed remains constant.

    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: B

    Solution :

                        We can multiply any vector by any scalar.                 For example, in equation \[\vec{F}=m\vec{a}\] mass is a scalar quantity, but acceleration is a vector quantity.
