The charge in coulombs on 1 g ion of N^(3-) is

The unit of charge is coulomb in SI system and esu of charge (or stat coul) in C.G.S. system 1 coulomb equals

Two charges Q_(1) and Q_(2) coulombs are shown in figure. A third charge Q_(3) coulombs is moved from points R to S along a circular path. Change in potential energy of the charge is -

If 4 xx 10^(20)eV energy is required to move a charge of 0.25 coulomb between two points. Then what will be the potential difference between them ?

Find the charge in coulombs required to convert 0.2 mole VO_(3)^(2-) into VO_(4)^(3-)

Two charges are at distance (d) apart in air Coulomb force between them is F. If a dielectric material of dielectric constant (K) is placed between them, the coulomb force now becomes.

A lamp draws a current of 2.0 A. Find the charge in coulombs used by the lamp.

There are two equipotential surafce as shown in figure. The distance between them is r . The charged of -q coulomb is taken from the surface A to B, the resultant work done will be

If two charges of 1 coulomb each are placed 1 km apart, then the force between them will be
