Some planetary scientists have suggested that the planet mars has an electric somewhat similar to that of the earth, producing a net electric flux of 3.63X10^16 N*m/C at the planet's surface. Calculate: a) the total electric charge on the planet; b) the electric field at the planet's surface ( refer to the astronomical data inside the back cover);c) the charge density on Mars, assuming all the charge is uniformly distributed over the planet's surface. please walk me steps and detail.
