Electrocardiography and lightning: Putting it all together

Heart’s dipole charge The heart has a dipole charge distribution with a charge of +1.0 x 10^-7 C that is 6.0 cm above a charge of -1.0 x 10^-7 C. Determine the field (magnitude and direction) caused by the heart’s dipole at a distance of 8.0 cm directly above the heart’s positive charge. All charges are located in body tissue of dielectric constant 7.0. What is the force exerted on a sodium ion (charge +1.6 x 10^-19 C) at that point?
