Study Notes
Electric Field of a Dipole
- As the distance from the dipole increases, the electric field on the axial line of a dipole decreases.
Electric Field Calculation
- The formula to calculate the electric field due to a dipole on its axial line is: E = k * p / r^3, where E is the electric field, k is Coulomb's constant, p is the dipole moment, and r is the distance from the dipole.
Electric Field at Large Distances
- At a very large distance from the dipole, the electric field on the axial line of a dipole approaches zero.
