The pressure of gas in cathode ray tube is

The density of air at normal atmospheric pressure is 1.293kgm^(-3) . What would be the density of air at a pressure of 10 atmospheres?

The mean free path of electrons in the gas in a discharge tube is inversely proportional to the pressure inside it. The Crookes dark space occupies half the length of the discharge tube when the pressure is 0.02 mm of mercury. Estimate the pressure at which the dark space will fill the whole tube.

Assertion : The characteristics of cathode rays do not depend upon the material of electrodes and the nature of the gas present in the cathode ray tube. Reason : Cathode rays consist of negatively charged particles, called electrons.

The atmospheric pressure at a given place is dependent on

Assertion (A), study of discharge of electricity through gases at low pressure resulted in the discovery of cathod rays . Reason (R ): cathod rays are deflected by both magnetic and electric fields and the direction of deflection shows that they are nagatievly charged .
