72. We denote the electron with subscript e and the proton with p . From the figure below we see that G G E E e d e p = = 4 0 2 π ε where d = 2.0 × 10 –6 m. We note that the components along the y axis cancel during the vector summation. With k = 1/4 πε 0 and 60 θ = ° , the magnitude of the net electric field is obtained as follows:

    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.
