Find the electric flux through the plane surface shown in the figure below if θ = 63.6°, E = 339 N/C, and d = 5.40 cm. The electric field is uniform over the entire area of the surface.

A hollow sphere of radius .05m contains a negative charge sitting right at its center. (The sphere itself is not charged.) The electric field everywhere on the surface of the sphere has the magnitude 3.0*10^-4 N/C. Draw the sphere and show the electric field vectors on your drawing. What is the total electric flux through the surface of the sphere?

Consider a closed triangular box resting within a horizontal electric field of magnitude E = 8.26  104 N/C as shown in the figure below. (a) Calculate the electric flux through the vertical rectangular surface of the box.

The square surface shown in the figure measures 3.4 mm on each side. It is immersed in a uniform electric field with magnitude E = 1400 N/C and with field lines at an angle of 35° with a normal to the surface, as shown. Take that normal to be "outward," as though the surface were one face of a box. Calculate the electric flux through the surface. Normal 4 Number i Units
