Earth's atmosphere is constantly bombarded by cosmic ray protons that originate somewhere in space. If the protons all passed through the atmosphere, assume that each square meter of Earth's surface would intercept protons at the average rate of 1200 protons per second. What would be the electric current intercepted by the total surface area of the planet?
