01. - Calculate the absolute potential at the point P in the figur..

03. - If a piece of metal has a charge +0.1 m C and is placed inside a hollow metal sphere of radius 20 cm (with touching it), what is the potential of the sphere? What will the potential of the sphere become, if a) the sphere is temporarily Earthed and then left insulated? b) if the metal subseque..

07. - Calculate the area of the plate of one Farad parallel plate capacitor if the separation between the plates is one millimetre and plates are in vacuu..

09. - Assume the radius of electron same to the radius of proton which is 10 - 1 5 m. Let the electron charge reside on the surface. What is the potential energy of such as charge distribution? Also, calculate the relativistic mass equivalent of this energ..

When a gas or an air stream containing aerosols in the form of dust, fumes or mist, is passed between two electrodes, then, the aerosol particles get precipitated on the electrode. Electrostatic Precipitator The following practices also help in controlling air pollution: Better desi..

The electrostatic potential is defined as the work done in bringing a single positive charge from infinity to a point in the electric field. Any point outside the electric field or space is called infinite poin..

Electrostatic Potential - The electrostatic potential is defined as the work done in bringing a single positive charge from infinity to a point (Any point outside the electric field or space is called infinite point). The unit of potential is volt (symbol V). Electric potential ..

All materials are broadly classified into two categories, one conductors and other insulators. When a conductor is placed in a electric field, there is a large scale of physical movement of free electrons, within the conductor and they move out only if we make arrangements for it. Insulators are ca..
