Calculate the coulombic force (in Newtons) felt by an electron and a proton separated by a distance of 1 angstrom. An angstrom is 10-10 meters.

F=kq'q"/d²

charge of electron (q') = 1.6022*10^-19

charge of proton (q") = - 1.6022*10^-19

Coulomb's constant (k) = 9*10^9

distance (d) = 10^-10

substituting values into equation

F = (9*10^9) * (1.6022*10^-19) (-1.6022*10^-19) / (10^10) ²

F = - 2.31034036 * 10^-48N
