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,..

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..

They get deflected by electric and magnetic fields. The deflection is large since a beta particle is lighter than an a -particle. They affect photographic plates. They ionise the gas through which they pass. The mass is 9.1 x 10 - 3 1 kg and its charge i..

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..

An electron is found to carry 1.6 x 10 -19 coulomb of negative charge. This is the smallest negative charge known to be carried by any particle, and is consequently taken as the unit negative charge. The relative charge of a electron is -1 (minus on..

Electric Charge - 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 fr..

Electric Charge - 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 ..

Atomic Structure and Charges - The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutrons..

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..

(v x B) is normal to v and work done by it is zero. In a uniform magnetic field B, the charge q described in (7) executes circular orbit in the plane normal to B. Its frequency of uniform circular motion is called the cyclotron frequency and is given by: This frequency is independent of t..
