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

Answer

(c) 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.
