A given charge is situated at a certain distance from an electric dipole in the end on position experiences a force F. If the distance of the charge is doubled, force acting on the charge will be

Determine the potential at a distance r from a point charge +q. How can the potential at a point be determined due to a number of point charges?

The number of electrons in 2 coulomb of charge is-

The electrostatic force between two point charges and the gravitational attractive force between two point masses- both are inversely proportional to the square of the distance between the charges and the masses, respectively. (1)(a) Compare the eletrostatic force (F_(C)) and the gravitational force (F_(G)) between an electron and a proton. (b) Compare F_(C) and F_(G) between two protons. (ii) Find out the accelerations of an electron and of a proton due to the electrostatic force between them when htey are placed at a distance of 1 Å

Show that the tangential component of electrostatic field is continuous from one side of a charged surface to another.
