1. The problem statement, all variables and given/known data a) Sketch the electric field pattern setup by a postively charged hollow sphere. Include regions inside and regions outside the sphere. b) A conducting cube is given a positive charge. Sketch the electric field pattern both inside and outside the cube. 3. The attempt at a solution a) No electric field lines inside both objects. b) My teacher said for the cube, the lines radiating outwards: Except they’re more bunched up around the corners. Can someone explain what that is suppose to mean? Should I draw my pictures in 3d or 2d? Please tell me if I'm doing this right.
