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) Quantisation (c) Conservation Coulomb's law: the Ele..
Vectors - Introduction
A change of position of a particle is called displacement. If a particle moves from a position A to a position B, as shown in the figur..

If a small compass needle is placed at a point near the north pole of a bar magnet, the needle turns round on its pivot and settles in a fixed direction as shown in figure. At other points away from the pole the needle settles tangent to the field lines shown. The magnet exerts ..

Magnetic field is a region near a magnetised body where magnetic forces can be detecte..
Electric Field Lines
Electric Field Lines - Michael Faraday (1791 - 1867) introduced the idea of lines of forces. They are nothing but a way of pictorially mapping the electric field around a configuration of charges. It is the curve drawn in such a way that the tangent to it at ..
Magnetic Field Lines
The compass needle always lies along the direction of the field. The figure below shows the lines or pattern of the field, when the compass needle is placed at several places. These lines do not really, tell us the effect that magnet has on the other. These h..

Collinear vectors are those vectors that act either along the same line or along parallel lines. These vectors may act either in the same direction or in opposite direction..
Dot Product of Vectors and the Resolution of a Vector
It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass and temperature, so also it is ..
Magnetic Field
. These patterns indicate the magnetic field of the magnet. A magnetic field is represented graphically by lines of force. The iron filings align themselves in a particular pattern which represents the magnetic field lines..

Tutor Vista teachers were knowledgeable and good in explaining to kids with 100% correct answers.... Landon
Better than great. That was the best 45 minutes i have spent on here. We got a lot done and i have a better understanding of the material. Thanks
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
this tutoring helped me with each and every problem i needed help with and helped me to understand the math - ben
