The International Space Station (ISS) travels with speed v=10 km/s during low earth orbit where there is a free charge density of 10^5 elch/scm^3. The ISS has a cross-section of 900 m^2.
1. What is the current (in Amps) impinging on the ISS?
2. The capacitance of the ISS has been calculated to be 1000 nF. If the ISS is initially grounded (V=0), what would the ISS voltage be after 1 second?
