Solution
The correct option is B Bernoulli's principle
Answer is A.
The working of spray-gun is based on Bernoulli's principle. When the rubber bulb is squeezed, air is blown into the tube A, due to which, low pressure and high velocity is created. Since this pressure is less than the atmospheric pressure, the liquid is pushed up. This rising liquid is sprayed out of the nozzle 'N', due to the blowing air.
The diagrammatic representation is shown.
