for this problem i do not know how to start it, i believe that the 7.31 value is the charge density but i do not know what the other value Eo would be. once i can solve for the first part i will be able to calculate for the magnitude of the electric force
Homework Statement
The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. Assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.31 x 10-6...
electrostatic force?
Homework Statement
Two very small spheres are initially neutral and separated by a distance of 0.50 m. Suppose that 6.2 x 1013 electrons are removed from one sphere and placed on the other. What is the magnitude of the electrostatic force that acts on each sphere...
