Charging by Friction
). The charge on an electron is known to be e = -1.6 x 10 - 1 9 C. This is the smallest value of charge which exists in nature. The charge on a proton is equal to + 1.6 x 10 -19 C. If 'n' number of electrons are transferred from one body to another by rubbing..
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 friction) of suitable material..

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 neutron..
Electric Charges and Field
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 ..
Electric Charges and Field Summary
Summary - Electric charge is a basic property of all matter. Unlike charges attract, like charges repel. Conductor allow flow of electric charges through them while insulators don't. Electric charges have three basic properties (a) Additivity (b) Qu..
Characteristics of Beta Rays (i.e., b - Particles)
Beta rays are made up of streams of negatively charged particles similar to electrons. Thus, - particle has a unit negative charge and a negligible mass. They are electrons. Hence, - particle is represented as -1 e 0 . They affect photogra..

Discovery of Neutrons
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 ..
Electricity and Matter
It is important to know the atomic picture of matter. The basic unit of all matter is an 'atom'. Each atom consists of a small core called nucleus which accounts to most of its mass consisting of positively charged protons and neutral neutrons and surrounded by lighter neg..
Structure of the Atom
Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J..

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.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
My son really liked the tutors approach! thanks so much he left the computer feeling postive and confident about his test tomorrow. and that make us (mom and dad) happy!!!!!!
i loved the session... she was a great tutor.. she helped me alot and now i have a good understanding of fractions.. thank you! :)
