What is the magnitude of electric intensity due to a dipole of moment `2xx10^(-8)C-m` at a point distant `1 m` from the centre of dipole, when line joining the point to the center of dipole makes an angle of `60^(@)` with diople exis ? |
Answer» Here, `p = 2xx10^(-8) C-m, r = 1 m`, `theta = 60^(@), E = ?` `E = (p)/(4pi in_(0) r^(3)) sqrt(3 cos^(2) theta+1)` `= (2xx10^(-8)xx9xx10^(9))/(1^(3)) sqrt(3 cos 60^(@) + 1)` `E = 238*1 N//C` |
