JEE Main & Advanced Physics Communication System / संचार तंत्र Question Bank Assertion and Reason

  • question_answer
    Assertion             :       The television broadcasting becomes weaker with increasing distance. Reason                 :       The power transmitted from TV transmitter varies inversely as the distance of the receiver

    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: C

    Solution :

                As the distance increases, TV signals becomes weaker. So assertion is true. The power transmitted from TV transmitter is inversely proportional to the square of the distance of the receiver. That's why reason is false.
