As light is transverse in character, all directions of vibrations of electric vector in the unpolarised light are confined to the XY plane. While looking along the X axis, vibrations of electric vector parallel to Y axis are seen and simil..

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) Conse..
Electric Field Due to a System of Charges
Consider a system of charges q 1 , q 2 , ..q n placed at distances r 1 , r 2 , ..r n with respect to some origin. Then the electric field intensity due to all these charges at a point is found out using the intensity due to the number of charges q 1 , q 2 , ..q n . Then the give..

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..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Tutor helped me on every question and help me when i was confused. Thank you Tutor Vista
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.
I like the way this tutors double check the work with me and took time to explain each detail. It really helped me to better understand - Harry
