An electron and a proton are m apart. Calculate their dipole moment if they are

Question

  An electron and a proton are                                    m apart.  Calculate their dipole moment if they are at rest. Using your dipole moment calculation, find the electric potential at a point m away when this point is along the axis of the dipole nearer the positive charge and when this point is 45o left of the axis but nearer the negative charge.

An electron and a proton are m apart. Calculate their dipole moment if they are at rest. Using your dipole moment calculation, find the electric potential at a point m away when this point is along the axis of the dipole nearer the positive charge and when this point is 45o left of the axis but nearer the negative charge.

Explanation / Answer

Use coulomb's law:

F=k [(q1q2)/r^2]

k~8.988 x 10^9 Nm^2/C^-2
q1=charge of particle one (proton)
q2=charge of particle two (electron)
r=distance between them
