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..
Equality of Vectors
> If the scales selected for the representation of three vectors are the same, then, three equal vectors are represented by three arrows of equal lengths, pointing in the same direction. If, however, the scales chosen are different, then, it is possible to represent equal v..

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 meani..
Gravitational Field
Gravitational Field - The space around a body within which its gravitational force of attraction is experienced, is called its gravitational field..
Space Exploration Conclusion
Conclusion - Unfolding the mysteries of the dark and silent space with no known boundaries has always been a dream of the human race. The desires of man has ultimately been accomplished through the exploration of space using various space launching vehicles, space..

Relationship between Electric Field and Potential
The above figure shows the electric field of a positive point charge. The electric field is directed away from the charge and potential is positive at any finite distance from the charge. If we move away from the charge, i.e., in the direction of the elect..

Dipole in an external field Consider a permanent dipole of dipole moment 'p' in a uniform external field E, which implies that p does not depend E nor it is induced due to E. The force on q is qE and on -q is -qE and net force on dipole is zero. However, the charges ..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
You are an amazing tutor. So knowlegeable and patient. Very clear in explanations, 2 thumbs up -kelly
