Question

In hydrogen atom the electrical force of attraction between the electron and proton is 8.1×10^-8 calculate the distance between the electron and proton.. given charge on electron is 1.6×10^-9

Answer 1

Explanation:

The magnitude of charge on electron and proton is same and equal to 1.6×10−19C i.e. q1=q2=1.6×10−19C. The distance between the two chargesis r=0.05 nm=0.05×10−9m . Hence, theelectrostatic force of attraction betweena proton and an electron in a hydrogen atom is 9.216×10−8 N .
