A tetrahedron has an equilateral triangle base with 20-cm-long edges and three equilateral triangle sides. The base is parallel to the ground, and a vertical uniform electric field of strength 200 N/C passes upward through the tetrahedron. (a) What is the electric flux through the base? (b) What is the electric flux through each of the three sloping sides?
