The charge on an electron is −1.6×10−19 c. the charge on a proton is equal in magnitude, but positive. the electron's mass is 9.11×10−31 kg.

a. in an atom, the electron and the proton and electron are seperated by about 0.5 angstroms, 5.0×10−11 m. what is the acceleration of an electron of an electron in an atom?

b. what is the electric field magnitude due to the proton at the electron's location?

c. the "dielectric strength" is the electric field magnitude at which a substance begins to spark. air begins to conduct or spark when the electric field is about 3 million n/c. how does this electric field compare to the magnitude of the electric field in an atom?

1. the electric field in an atom is much less than the dielectric strength of air
2. the electric field in an atom is much greater than the dielectric strength of air
3. the electric field in an atom is within an order of magnitude (a factor of 10) of the dielectric strength of air
