How to remember derivations from electrostatics and what type of questions are generally asked from this lesson???

							
@ shreyas 
the derivation of electrostatics are usually based on assumption . as u need to know the correct position of charged particle and the coordinate system . 
steps of learning derivation 
1- read the derivation statement twice . 
2- write what u need to proov and to end up with final conclusion . 
3- draw the diagrams . 
4- remember of the relation or equation u have studied before , 
5- apply that and formulate an new equation , thats it . 
USE ALL IN ONE , THEY ARE PRECISE AT ITS LEVEL . 
MAIN FOCUS AREA OF ELECTROSTATICS . 
1- GAUSS LAW ( 3 CASES ) – VVIMP . 
2- WORK DONE BY CHARGE PARTICLE IN SPACE , 
3- DIELECTRICS INSERTED BETWEEN THE CAPACIRTOR PLATE – VVIMP 
4- PARALLEL PLATE CAPACITOR IN NORMAL – IMP 
5- FINDING THE EQUATION WHEN CHARGHED PARTICLE WILL COMBINE AT A SPACE . 
THESE 5 are very very imp catagory of electrostatics , dereivation , some other are there but not that imp . 
board can also ask u a question based on series and paralklel config of capacitor , config of dielectrics , 
and the property of equipotential surface . 
so, mainly focus on these area . 
ALL THE BEST ..
