Millikan measured the electron's charge by observing tiny charged oil drops in an electric field. Each drop had a charge imbalance of only a few electrons. The strength of the electric field was adjusted so that the electric and gravitational forces on a drop would balance and the drop would be suspended in air. In this way the charge on the drop could be calculated. The charge was always found to be a small multiple of 1.6e-19 C. Find the...

A negatively charged oil drop whose mass is 10-15 kg and
whose charge is -6.4 10-19 Coulombs remains stationary under the
influence of the Earth’s gravitational field and a uniform external
electric field made by two oppositely-charged parallel plates (see
diagram below). Ignore the influence of Earth’s electric field on
the oil drop.
Determine the magnitude and direction of the net
electric field created by the plates (not the electric field of the
oil drop !). Explain completely how you...

The heart has a dipole charge distribution with a charge of +1.0×10−7C that is 6.1 cm above a charge of −1.0×10−7C. A) Determine the magnitude of the E⃗ field caused by the heart's dipole at a distance of 8.5 cm directly above the heart's positive charge. All charges are located in body tissue of dielectric constant 7.0. The answer is not 82.34x10^3 N/C that answer would be correct if the charges were located in the air. the given charges are...
