    How Does Charge Distribution Affect Electrostatic Energy and Potential?

    1. Four charges are placed at the corners of the square where the opp diagonals have +2microcoulombs and -2 coulombs. what is the electrostatic energy of the system? ANS: -4.7 J 2. Two conducting spheres that carry equal charges are very far from each other and from all other charges. One...

    What Happens if Earth Had a Net Surface Charge Density?

    The rest came easily thereafter too. Easier than I thought- simple plug in and solve!

    What Happens if Earth Had a Net Surface Charge Density?

    1. If the Earth had a net surface charge density of 1.0 electron per square meter a) what would be the total charge on the Earth's surface? b) what would be the electric potential and c) what would be the electric field, just outside the Earth's surface? Attempt: I tried using...
