Question

# Deflection of anode rays is maximum when the discharge tube is filled with hydrogen gas.

A

True

B

False

Solution

## The correct option is A True The deflection of the anode rays depends on the nature of the gas taken in the discharge tube. Heavier the gas lower is the deflection. Hydrogen is the lightest gas. Hence the deflection of the anode rays produced due to hydrogen gas is maximum.
