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.
The Attempt at a Solution

No electric field lines inside both objects.
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.
