movement 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,..

When a colloidal solution is viewed through a powerful microscope, the colloidal particles can be seen moving in a random zig-zag path. This zig-zag motion of colloidal particles is called Brownian movement. This random motion is due to collisions between the colloidal..

Brownian movement was first discovered by Robert Brown, a botanist, in 1827. He observed that pollen grains in water do not remain at rest but move about continuously and randomly. This random continuous movement (Brownian motion) was observed in colloidal sol when the sol was ..

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 gas through which th..

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..

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..

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..

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..

The particles present in matter are not stationary, but have a tendency to acquire motion. In fact they are in a state of continuous motion. The rate of movement of the particles is directly proportional to the thermal energy of the particles..
