9. At points between the charges, the individual electric fields are in the same direction and do not cancel. Since charge q 2 = 4.00 q 1 located at x 2 = 70 cm has a greater magnitude than q 1 = 2.1 × 10 8 C located at x 1 = 20 cm, a point of zero field must be closer to q 1 than to q 2 . It must be to the left of q 1 . Let x be the coordinate of P , the point where the field vanishes. Then, the total electric field at P is given by ( ) 2 1 2 2 0 2

### What students are saying

• 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.
