WebThe first metal sphere has 100 excess protons and touches a metal sphere with 50 excess protons, so the second sphere transfers 25 electrons to the first sphere. These 25 extra electrons will electrically cancel 25 protons so that the first metal sphere is left with 75 excess protons. This is shown in the bottom row of Figure 18.10. Web29 aug. 2007 · Sphere 1, sphere 2, and sphere 3 have charges. 75 µC, −44 µC, and 50 µC, respectively. Each sphere is separated by 0.15 m. What is the net electric force on the middle. Initially, both metal spheres are neutral. In a charging process, 1 × 1013 electrons are removed from one metal sphere and placed on a second sphere. Web2.
