According to one of the first models (Thomson's model), the hydrogen atom is a sphere uniformly charged with positive electricity, in the center of which there is an electron. In general, the atom is neutral. Find the radius of such an atom if it is known that the minimum energy that must be imparted to an electron to remove it from the atom over a large distance is equal to Wi. Electron charge e. Indication. Take into account that a uniformly charged spherical layer does not create an electric field in its internal cavity.
