A) 4.1 104 N/C
B) 8.2 104 N/C

Question 2
A geophysicist measures the magnetic force on a proton that is moving vertically downward at a point 1.996 km/s at the earth's equator. At that location, the earth's magnetic magnetic field is horizontal and has a strength of 0.40 10-4 T.
What are the magnitude and direction of the force she will measure? (e = 1.60 10-19 C)

Mass Loss from a Supermassive Star
Due to compressibility, atmospheric mass gradually “thins out” with height.
Pressure is a result of the atmosphere’s mass.
