What Is Electric Potential Energy? Electric potential energy is the form of energy that a charge has because of its position in an electric field. It is the work done by an external force to bring the charge from infinity to a certain point against the electric field. Electric potential energy depends on the charge … Read more
electric field due to a dipole along the axial line To derive the electric field due to a dipole along the axial line, we can follow these steps: \(\displaystyle E_1 = \frac{1}{4\pi\epsilon_0}\frac{q}{(r-a)^2}\) The direction of \(E_1\) is along \(\vec{OP}\), where \(O\) is the origin. \(\displaystyle E_2 = \frac{1}{4\pi\epsilon_0}\frac{q}{(r+a)^2}\) The direction of \(E_2\) is along \(\vec{OP’}\), … Read more
Introduction An electric dipole is a system of two equal and opposite electric charges that are separated by a small distance. An electric dipole has a property called the electric dipole moment, which is a vector that measures the magnitude and direction of the charge separation. The charges, one positive and one negative, create a … Read more
