The charge and mass of the positive 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..
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. As the protons are positively char..
Properties of alpha particles
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..
Wave Nature of Particles
. The radiation has a dual aspect behaving either as waves or as particles (waves when it interferes, diffracts and particles in a photocell). Einstein showed that a particle having a finite mass has been supposed to be associated with a definite amount of en..
Charge of an Electron
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
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..

Summary - The centre of mass is an imaginary point where one can assume the entire mass of the given system or object to be positioned. Principle of conservation of linear momentum states that the linear momentum of a system remains constant if the external forces acting on the system add up to zer..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
