electrostatic charges

In a static situation, when a conductor is charged, the excess charges reside only on the surface. If we consider any arbitrary volume inside a conductor, the electrostatic field on closed surface bounding the arbitrary volume is zero. Thus, the flux through the surfa..

>As the path is independent of work, the potential energy of two charges q 1 , q 2 located at r 1 and r 2 in an external field is given ..

It states that "the electrostatic force between two electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them ..

Metals have high tensile strength. Metals can resist stretching without breaking. A strong electrostatic attraction between the positively charged kernels and the mobile electrons surrounding them is the reason for tensile strengt..

While charging a capacitor, a battery transfers positive charge from negative to the positive plate. So some work is done in transferring this charge, which is stored in the capacitor in the form of electrostatic energ..

The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that poin..

Photocopier moves a document from the handler to the glass plate, where the pattern of the image is projected by lamps, mirrors and lenses onto a photoreceptor belt (or drum). The electrostatic charge on the belt fades in areas receiving light from the projected image. Magnetic..

Potential Energy: is the work done at a point by an external agent in moving a unit positive charge from infinity to a given point against the electrostatic fiel..

These types of forces occur in molecular solids which have polar molecules. A polar molecule has separate centres of positive and negative charges. These forces arise due to electrostatic attraction of the other molecule and vice-versa (The positive end of one molecule attracts..
