electrically charged particles

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 experiments...

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 ..

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 cha..

The principle of quantisation of electric charge states that "in nature there is a smallest amount of charge and all other charges are integral multiples of this smallest unit ". That is, if e is the minimum charge then the total charge o..

Two Kinds of Electric Charges - You can electrify a glass rod by rubbing it with silk. Suspend such an electrified rod by a silk thread as shown in figure. If you bring another glass rod electrified in the same manner, you will notice that the rods repel each othe..

Consider a charge Q at the origin of the co-ordinate system. Let a test charge q be placed at a distance r from the origin. ..

If a system consists of two point charges q 1 and q 2 , then the total charge of the system is got by adding q 1 and q 2 . Thus, the charge add up like real numbers (scalars). When we add charges, one should take care of its sig..
