One of the Echo satellites consisted of an inflated spherical aluminum balloon 30 m in diameter and of mass 20 kg. Suppose a meteor having a mass of 9.2 kg passes within 4.4 m of the surface of the satellite. What is the gravitational force on the meteor from the satellite at the closest approach?

    Use Newton's universal law of gravity,

    F = G M1 M2 /R^2

    M1 and M2 are the two masses

    R must be measured center to center, so in this case R = 19.4 m

    Solve for F

    You may have to look up the universal constant G
