Calculate the electrostatic force (Fe) between two electrons separated by a distance of 1.00 × l0^– 8 meter? Each electron has a charge of -1.6 x 10^-19 C. Show work, formula, known, unknowns, answer.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
