deflection of charged particles

The e/m ratio of the anode rays obtained from hydrogen gas was found to be highest and equivalent to 9.58 x 10 4 C g - 1 . These particles carried a charge of 1.602 x 10 - 1 9 C. Thus, the mass of the positive particle from hydrogen gas is,..

They are deflected by electric and magnetic fields. The deflection is less compared to that of b particles, because a particles are heavy. They affect a photographic plate and cause fluorescence on striking a fluorescent material. They ionise the ..

When an electric field is applied in the path of cathode rays, they are deflected towards the positive plate of the electric field, which shows cathode rays are made up of negatively charged particles..

Although Rutherford's model was enormously successful at explaining the scattering of alpha particles, there was a problem when the experimental data were used to calculate the mass of the nucleus. From the results of the scattering experiments, it was possible to calculate the char..

An electron is found to carry 1.6 x 10 - 1 9 coulomb of negative charge. Since this is the smallest negative charge carried by any particle, it is taken as unit negative charge..

The proton has an equal and opposite to the charge of an electron. So, the absolute charge of a proton is 1.6 x 10 -19 coulomb of positive charge. This being the smallest positive charge carried by any particle, it is taken as 1 unit positive ..

It is very difficult to define, what an electric charge is? The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable material..

Beta rays are made up of streams of negatively charged particles similar to electrons. Thus, - particle has a unit negative charge and a negligible mass. They are electrons. Hence, - particle is represented as -1 e 0 . They affect photogra..

Why colloidal particles get charged? There are various reasons: i) Due to friction between the colloidal particles and molecules of dispersion medium, the colloidal particles become charged. ii) Charges on colloids appear due to preferenti..

The word 'electric' is derived from the Greek word 'elektron' meaning amber. The existence of charges were known when charged particles were produced by rubbing (due to friction) of suitable materials. These facts are demonstrated by simple experiment..
