2. consider a flat plate with a surface area of 100 m2, placed at the low earth orbit (leo) (you can assume the relative velocity between the flat plate and ambient plasma is orbit velocity the ambient plasma (ion species is o+) has the following parameters: n ev, b = 0.33 gauss. the leo velocity is 7.3 km/s. 1x1 3, te t0.1 a) verify that the plate "sees" a meso-thermal plasma flow and calculate the plasma flow mach number based on the ion acoustic velocity. b) if the plate is directly facing the plasma flow (90g angle of attack), calculate the ion flux density to the solar panel, the floating potential of the solar panel, and the sheath thickness for the ram side using 1-d calculation. comment whether the 1-d simplification is a good or bad approximation. (hint: in this case, the ions enter the sheath with a drifting velocity of 7.3 km/s)
