The idea that everything is made up of very small particles has been developed over many years supported by several experiments: (i) Brownian motion :
An alpa particle is directed vertically upward with a speed of 3 X 104 Km/Sec in a region where a magnetic field of magnitude 1 Tesla exists in the direction south to north. Determ
