Heart’s dipole charge. This question refers to the heart and ECG. There is a PDF from textbook on this situation.

A) For dipole described in the problem below, draw the Electric field lines of the dipole. Don’t worry about the dielectric.

B) What’s the ECG measure?

C) Why is it important for the ECG pads to have good electrical conduction. That is, why do they put that ointment on your skin when they place the pads? I solved this problem in class.

D) The heart has a dipole charge distribution with a charge of +1.0 * 10-7 C that is 6.0 cm above a charge of -1.0 * 10-7 C. Determine the E 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 = +e = +1.6 * 10-19 C) at that point?

An electron is released from rest on the axis of an electric dipole that has charge e and charge separation d = 33 pm and that is fixed in place. The release point is on the positive side of the dipole, at distance 9.4d from the dipole center. What is the electron's speed when it reaches a point 3.2d from the dipole center?
