Static Electricity 1. One of the Mars Rover vehicles, Sojourner, collected red Martian dust on its wheels as it
rolled along. There is very little water on Mars, so it's not mud; it's actually dust. Explain, in
detail, why the dust clings to the wheels. Be sure to describe forces by name and mention
charging by induction, conducting, or rubbing, if it is appropriate. Also explain what atoms on
Mars must be composed of. (4 points)
