Question

Calculate the electric potential due to a tiny dipole whose dipole moment is 6.0×10−30 C⋅m at a point 5.1×10−9 m away for the following cases.
(a) This point is along the axis of the dipole nearer the positive charge
(b) This point is 45 ∘ above the axis but nearer the positive charge.
(c) This point is 45 ∘ above the axis but nearer the negative charge. Let V=0 at r=∞.
