1. The problem statement, all variables and given/known data A point charge Q is located at the origin. The point charge produces an electric field at a radius of 2.0 meters from the origin of 20N/c.The electric potential of a spherical surface of radius 3.0 meters around the point charge is, in Volts. 2. Relevant equations E=kq/rs, [tex]\varphi[/tex]=Q/[tex]\epsilon[/tex]o 3. The attempt at a solution I'm really not sure where to go with this. I'm not sure how to use gauss' law here (if i even should). Also, I'm very confused about how to convert this into electric potential. This is totally something I could clear up in like 5 min in office hours or something, but I'm deployed in Iraq right now so can't do that Thanks a ton!!!
