<span>Since you did not show any
picture, I will be describing Dalton’s atomic theory. The scientist thought
that the atom was the smallest particle in the universe is John Dalton. He
established five theories relating atoms. One, elements are made of extremely
small particles called atoms. Two, atoms of different element have different
sizes, mass and physico – chemical properties. Three, atoms cannot be divided
further, destroyed or created. It also follows the law of conservation of
energy. Fourth, atoms can combine to form compounds. And lastly, in chemical
reaction, atoms can be combined, separated or rearranged. </span>
Suppose protons were emitted rather than electrons then it affects the experiment as the mean velocity of proton will be less then mean velocity electron .
The mass of proton is greater than the mass of electrons but charge of electron is equal to the charge of proton . So , due to difference in the mass of electron and proton there will be some effects. We can conserve the electric energy which is equal to the qe .
The kinetic energy = 1/2
Now changing the electric potential energy into kinetic energy
v = √2qe/m
The mean velocity of proton will be less then mean velocity electron .
