Equation 18 from the website: |If we consider the case where r=>a then pcos vV s an again since pcosB= p-r\" where, r" is the unit vector along the vector OR then electric potential of dipole is pr Vim0 4;a=:or1 as for r==a From above equation we can see that potential due to electric dipole is inversly proportional to r2 not 1/r which is the case for potential due to single charge. Potential due to electric dipole does not only depends on r but also depends on angle between position vector r and dipole moment p. Start form the result of part (a), Prob 71, Ch 25, 8th edition, which is Prob 48, Ch24, in the 10th edition, which gives the potential of an electric dipole, find the expression of the electric field produced by the dipole, in terms of the vectors r and p (the dipole moment). Do not express the result in component forms. You can see the expression for the potential V of an electric dipole Start form the result of part (a), problem 71, Ch 25, 8th edition, which is the potential of an electric dipole, find the expression of the electric field produced by the dipole, in terms of the vectors r and p (the dipole moment). Do not leave the result in component forms. You can see the expression for the potential V of an electric dipole from this link (Eq. 18) : https:/physicscatalyst.com/elec/electric-potential-dipole.php Challenge Problems An electric dipolc is located along the y axis as shown in Figure P25.71. The magnitude of its electric dipole moment is defined as p = 2aq. (a) At a point P, which is far from the dipole (r >> a), show that the electric potential is i k.pcos@ l"2
