A flat rectangle is placed in a uniform electric field with a magnitude of 7.8 x 103 N/C. The electric flux through the rectangle when its face is 45º to the field lines is 89.75 Nm2/C. Find the width of the flat rectangle with a length of 9. 45cm. 3. A hollow sphere has an unknown charges distributed uniformly over its surface. At a distance of 0.63 m from the center of the sphere, the electric field points radially inward and has magnitude of 4.56 x103 N/C. How much charge is on the sphere?
