the command module of the apollo spacecraft can be modelled as a truncated cone with a base diameter of 3.90 meters, a diameter at the upper (apex) end of 1.30 meters, and a length of 3.50 meters. the magnitude and direction of the earth's magnetic field do not vary significantly over a distance the size of the spacecraft. if the spacecraft is oriented while in orbit so that its long axis is parallel to the earth's magnetic field, which has a magnitude of 0.500 x 10-4 t, what is the amount of magnetic flux which passes through the sloping sides of the spacecraft (that is, excluding the base and top surface)?
