When current flows through a conductor (something that has free electrons excess like a metal), a magnetic field is produced around it (i.e., the conductor acts like a magnet). This is the principle that is used in electromagnets (those huge magnets that are used in cranes in dumpsters). The...
I would like to give you a link. Remember about those NCERT textbooks I said. They provide free ebooks to :

Select class (or Grade in Australia from 6-12 recommended), select subject (6-10:Science, 11&12 : Physics)...
We can It is called electromagnetic induction. Just as we cannot create magnetic fields using point stationary charges, we cannot create electricity with a magnet at rest (We can but it requires that we move a conductor in a specific way near it). For more information try googleing...
Just like you said you may enter the data to questions such as
What all courses you have enrolled ?
Why did you enroll in those topics?
What all topics do you like and why?
Please do check this. I have attached a clearer image. Please do reply if the information was good. Thank you. Always happy to help. :) the variable of gravity g changes with height so the h should not be changed
I would suggest you to use basic high school physics and then go over to advanced ones the order that I would suggest for you would be:
1. Prentice Hall Conceptual Physics
2. NCERT Science Textbooks (Class 6,7,8,9,10)
3. NCERT Physics Textbooks (Class 11,12)
If you are in need of a deep study...
Dear Friend, the equilibrium position only depends on the magnitude of the two charges not their polarity thus the equation will change to:
x = L sqrt (|Q1|) / (sqrt (|Q2|) - sqrt (|Q1|))
