The electric field E, at one face of a parallelopiped is uni- form over the entire face and is directed out of the face. At the opposite face, the electric field E₂ is also uniform over the entire face and is directed into that face (as shown in Fig. ). The two faces in question are inclined at 30° from the horizontal, while E, and E₂ (both horizon- tal) have magnitudes of 2.50 x 104 N/C and 7.00 × 104 N/C. Assuming that no other electric field lines cross the surfaces of the parallelopiped, determine the net charge contained within. a. -67.50 C c. 105 o C u5 00 5 MOLDA 6.00 cm E ** Fig. 30° b. 37.5 80 C d. - 105 80 C Ē₂
