Question

= Pcos 4AEOT 3p sin cos e 4. A field line in the dipole field is described in polar coordinates by the simple equation r=ro sin, where ro is the radius at which the field line passes through the equatorial plane of the dipole. Show that this is true by demonstrating that for any point on the field line curve the tangential direction is the same as that of the electric field of the dipole. 418€gr3 F - P(3 cos? 0-1) 47€r3
