T=2pi(2m1*m2*l/q*E(m1+m2)) where m1 and m2 are the masses of the two charges..q is the charge l is the distance between them and e is the electric field...do you want the derivations to this...

Inside a sphere the potential is equal to ..........… Kq(3R^2-r^2)÷2R^3 where R is the radius of sphere r is the distance of point from center and q is the charge on the sphere Please let us know if...

@ ANSHUL yes, u can tell electric field of a point by knowing its potential becoz electric field is the negative of potential gradient.. Electric field will create at that time when one positive and...

Dear Student, You also please mention the name of the chapter. Thanks.

statCoulomb is the CGS unit of Electric Charge.The relation between statCoulomb and Coulomb is 1C=3*10^9statCoulomb.

if Not then This might be helpful- The amount of charge that can be placed in a capacitor is directly proportional to the voltage pushing the charge on the capacitor .the larger the potential...

If the two charges have the same sign, the electrostatic force between them is repulsive; if they have different sign, the force between them is attractive. An electric field is a vector field that...

Conductors are substances which allows current to flow. Examples : Copper, silver Silver is the best conductorof electricity. Most metals are conductors except lead and most of the non metals are...

Permittivity , also called electric permittivity , is a constant of proportionality that exists between electric displacement and electric field intensity. The permittivity of free space (a vacuum)...

The electron is a subatomic particle, symbol e− or β−, with a negative elementary electric charge . Electrons belong to the first generation of the lepton particle family, and are generally thought...

While Gauss' Law holds for all situations, it is only useful for "by hand" calculations when high degrees of symmetry exist in the electric field. Examples include spherical and cylindrical symmetry. ...
