if we introduce a conductor b/w the plates of a capacitor then what will happen? will the capcitance increase or decrease?

is proton volt = electron volt? if yes then why? even if proton is 1840 times massive then electron and eV Is work done in carrying an electron from one potentail difference to another when potentail differnece is 1 V.

why does an isolated atom not have a permanent dipole moment?

the concept of electric field lines are came into existence to satisfy the special theory of relativity which implies that action of electrostatic forces can not be instantaneous but takes some time to act on teh other charge i.e. if a charge produces an electric field then its effect will be...

In gauss' law, is E necessarily attributed to the charge q?

positive charges are sources of electric field and -ve charges are sink. what are sources and sink of gravitational fields?

is the electric field zero at points other than the middle of two simillar polarity charges and also other than infinity? if it can be zero then at waht points?

what is meant by the statement that"electrostatic forces obey the principle of superposition"

about electro static waves what is meant by the statement that "electro static waves follow the principle of super position"

why can't we make a black hole on earth. we know that a black hole comes into existence whenever a particles internal pressure becomes less than the outside pressure. the particle consequently collapses into itself and the creating a black hole, so why is it not possible on earth. then we can...

we have got four charges placed at the ends of a square. if we palce a positive charge in the center, it appeares to be in stable equillibrium; yet earnshaw's theorem(that no particle can be in stable equillibrium if it is under the action of electrostatic forces only) holds. Why is that?
