mention two difference between potential due to a point charge and potential due to an electric dipole.and also derive expression for the electric potential at a point on the extended axis of an electric dipole
Answers
Answer:
Derive an expression for electric potential at any point due to an electric dipole. Potential at point P due to the dipole along the equatorial line will be zero as P is equidistant from the two charges.
Explanation:
Electrostatic potential at a point due to an electric dipole
Consider two equal and opposite charges separated by a small distance 2a as shown in Figure 1.26. ...
Potential at P due to charge +q =
Potential at P due to charge –q=
Total potential at the point P,
By the cosine law for triangle BOP,
Since the point P is very far from dipole, then r>>a.
