Two electrons are (20 mm) apart at closest approach. What is the magnitude of the maximum electric force that they exert on each other? (e = 1.60 × 101° C, k = 1/47ɛ, = 9.0 10° N · m²/C³). -19 %3D

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

because if the tool that you are using is not balanced it there would be false mass.
