A point charge q is situated at X between two parallel plates which have a potential difference V and carry charges `+Q` and `-Q`. What is the electric field strength at X ?

The potential difference between two parallel plates 1 cm apart is 100V. The electric field strength between them is ?

If A is the area of each plate, charge on it is q and potential difference is V then the distance between the parallel plate capacitor is

A point charge Q is placed at point O. potential difference V_(A)-V_(B) is positive. Is the charge Q negative or positive ?

A battery is used to charge a parallel plate combination of two identical capacitors. If the potential difference across the battery is V and the total charge Q flows through the battery during the charging process then 1) The charge on each capacitor is Q/2 and the potential of each capacitor is V/2 2) The charge on each capacitor is Q and the potential of each capacitor is V 3) The charge on each capacitor is Q/2 and the potential of each capacitor is V 4) The charge on each capacitor is Q and the potential of each capacitor is V/2

Three point charges q, 2q and 8q are to be placed on a .9cm long straight line. Find the positions where the charges should be placed such that the potential energy of this system is minimum. In this situation, what is the electric field at the charge q due to the other two charges?

Two large conducting plates of a parallel plate capacitor are given charges Q and 3Q respectively. If the electric field in the region between the plates is E_0 , then the force of interaction between the plates is
