These rays travel in straight line.
They can be deflected by the applied electric filed. They are deflected toward the negative planet.
They are deflected at right angle to the axis joining the north and south poles.
e/m ratio for canal very ray is similar to the electron. e/m ratio of proton is dependent upon the nature of gas present in the tube. The e/m ratio for hydrogen gas in maximum. This is due to the fact that hydrogen gas has the smallest mass.
The charge of proton is equal to the charge on electron.
The mass of proton is . It is 1836 times of the mass of electron.

Like electron protons are also the fundamental particles of matter. From the study of the experiments of cathode ray tubes we can conclude that an atom contains two particles.

They are called as sub-atomic particles i.e particles smaller in size than the atom itself.
Since atoms are natural electrically, it can be said that the number of protons in a natural atoms should be equal to the number of electrons.
