Homework Help: Physics

Posted by Amy on Sunday, February 14, 2010 at 9:24pm.

On a clear day, the Earth’s atmospheric electric field near the ground has a magnitude of 100 N/C and points vertically down. Inside the ground, the electric field is zero, since the ground is a conductor. Consider a mathematical box of 1.0 m x 1.0 m x 1.0 m, half below the ground and half above. What is the electric flux through the sides of the box? What is the charge enclosed by the box?
