The vertically di- rected electric field has a uniform magnitude E at the top surface and 2 E at the bottom surface. 004 10.0 points A 40 cm diameter loop is rotated in a uniform electric field until the position of maximum electric flux is found. The flux in this position is measured to be 2.87 x 109 Nm2/C. What is the electric field strength? Answer in units of N/C. 005 10.0 points A spherical shell of radius 7.5 m is placed in a uniform electric field with magnitude 7000 N/C Find the total electric flux through the shell. Answer in units of N.m /C. 006 (part 1 of 3) 10.0 points An electric field of magnitude 4030 N/C is applied along the r axis. Calculate the electric flux through a rect- angular plane 0.412 m wide and 0.92 m long if the plane is parallel to the yz plane. Answer in units of N.m/C. How much charge Q is inside the box? 1. Qend = + Ea? 2. Qend = 0 3. Qend = 60 Ed? 4. Qend = 360 Ea? 5. Qend = 2 60 EGP 6. insufficient information 007 (part 2 of 3) 10.0 points Calculate the electric flux through the same rectangle if it is parallel to the ry plane. Answer in units of N.ma/C. 008 (part 3 of 3) 10.0 points Calculate the electric flux through the same rectangle if it now contains the y axis and its normal makes an angle of 33° with the x axis. Answer in units of N.m/C. 002 (part 1 of 2) 10.0 points A cylindrical shell of radius 7.6 cm and length 245 cm has its charge density uniformly dis- tributed on its surface. The electric field intensity at a point 20.4 cm radially outward from its axis (measured from the midpoint of the shell) is 59200 N/C. What is the net charge on the shell? The Coulomb constant is 8.99 x 10°N.m/C? Answer in units of C. 009 10.0 points A point charge of 6.2 C is located at the center of a sphere with a radius of 17 cm.
