The magnitude of electric flux is the same throughout the Gaussian surface. Is the statement CORRECT? d. Yes b. No c. Maybe 4. An electric field passes through a surface produces an electric flux which has a magnitude of 46N.m Find the magnitude of the electric field if the surface area is 0.04m. a. 1.64 N/C b. 1.74 N/C c. 1.84 N/C 5. An electric field (E=6.2N/C) passes through a flat surface area (0.50m) with an angle of 60'. What will be the magnitude of the electric flux? a. 1.6- N.m2 b. 2.64.m N.m C C c. 3.64 C1. Electron and proton are placed at two different locations (one charge at each location). The locations have the same electric potential. Do these charges have the same electric potential energy? a. Yes, if the electric potentials at the two locations are the same, the electric potential energies are also the same, regardless of the sign and magnitude of the charges placed at these locations. b. No, because the electric potential energy EPE at a given location depends on the charge placed at that location as well as the electric potential V. c. Both A and B d. None of the above 2.
