The H2+ ion is composed of two protons, each of charge +e= 1.6(10^-19)C, and  an electron, of charge -e and mass 9.11(10^-31)kg. The separation between the  protons is 1.07(10^-10)m. The protons and the electron may be treated as point  charges. a) Suppose the electron is located at the point midway between the two protons.  What is the potential energy of the interaction between the electron and the two  protons? (Do not include the potential energy due to the interaction between the  two protons.) U=  −8.60×10 −18 J b)Suppose the electron in part A has a velocity of magnitude 2.20

### 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.
