Homework Help: Mass of particules in the magnetosphere

  1. Mar 3, 2013 #1
    1. The problem statement, all variables and given/known data

    The problem is quite simple.
    Estimate the mass of particules that contains the earth's magnetosphere up to a distance of 100 times earth's radius (In the shadow cone of earth) and also up to the break point or stopping point of the side of the sun.The solar activity is at its minimum and the average density is 10 protons/cm³.Then compare with the total mass of earth's atmosphere.
    Thank you.

    2. Relevant equations
    Well the problem is that i can,t find any relevant equations that could help me with my problem

    3. The attempt at a solution
    The solar activity is at its minimum so the break point must be at a distance of approximately 10earth's radius. And that's were i stopped after hours of trying to figure out a solution.
    Thank you
