1 . [1 point, 10 tries] An electron is projected at an angle of 29.3° above the horizontal at a speed of 8.11×10 5 m/s in a region where the electric field is E = 396 j N/C. Neglecting the effects of gravity, calculate the time it takes the electron to return to its initial height. Answer: 1.14e-08 s 1 2 . [1 point, 10 tries] Calculate the maximum height it reaches. Answer: 1.13e-03 m 1 3 . [1 point, 10 tries] Calculate its horizontal displacement when it reaches its maximum height. Answer: 4.03e-03 m 1 4 . [1 point, 10 tries] A flat surface having an area of 3.48 m 2 is rotated in a uniform electric field of magnitude E = 5.88×10 5 N/C. Determine the electric flux through this area when the electric field is perpendicular to the surface. Answer: 2.05e+06 N*m^2/C 1 5 . [1 point, 10 tries] Determine the electric flux through this area when the electric field is parallel to the surface. Answer: 0.00e+00 N*m^2/C 1 6 . [1 point, 10 tries] A point charge of +4.97 µC is located at the center of a sphere with a radius of 14.5 cm.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
