Step 1
Given: Positive charge, q1 = 4.8 × 10^-19 C Distance from positive charge, r1 = 9.2 × 10^-10 m Using the formula for electric potential due to a point charge: \[ V_1 = \frac{k \cdot q_1}{r_1} \] where k is the electrostatic constant. Show more…

(II) Calculate the electric potential due to a tiny dipole whose dipole moment is $4.8 \times 10^{-30} \mathrm{C} \cdot \mathrm{m}$ at a point $4.1 \times 10^{-9} \mathrm{m}$ away if this point is $(a)$ along the axis of the dipole nearer the positive charge; $(b) 45^{\circ}$ above the axis but nearer the positive charge; $(c) 45^{\circ}$ above the axis but nearer the negative charge. Let $V=0$ at $r=\infty$.
(II) Calculate the electric potential due to a dipole whose dipole moment is 4.2 $\times$ 10$^{-30}$C $\cdot$ m at a point 2.4 $\times$ 10$^{-9}$ away if this point is (a) along the axis of the dipole nearer the positive charge; ($b$) 45$^\circ$ above the axis but nearer the positive charge; ($c$) 45$^\circ$ above the axis but nearer the negative charge.

An electric dipole consisting of charges of magnitude 1.50 $\mathrm{nC}$ separated by 6.20$\mu \mathrm{m}$ is in an electric field of strength 1100 $\mathrm{N} / \mathrm{C}$ . What are (a) the magnitude of the electric dipole moment and (b) the difference between the potential energies for dipole orienta- tions parallel and antiparallel to $\vec{E} ?$
