One of the communication frequencies that the InternationalSpace Station uses is 259.7 MHz. (a) Findthe gravitational frequency change with respect toEarth when the station is at its mean altitude of352 km. Assume g is constant and equal to 9.80 m/s2.(b) Now do a more precise calculation of the frequencyshift, without assuming that g is constant.
Electrostatics: Chapters 2122 Tuesday, September 9, 2014 2:44 PM Some things to explain in detail: A test charge is one that is small enough so that the charge configuration you are looking for is not disturbed. If you were to bring a 1μC charge up against some giant 1C charge, the smaller "test" charge would not really affect the position of the charge configuration you're studying. This leaves the equations dipole mentioned fairly easy to deal with. If, on the other hand, you put two 1C charges in proximity (or any charge of similar magnitude), the charge configuration will feel a strong enough force from the "test" charge that it will begin to move. If your charges move, your positions ar
