Consider the following very rough model of a beryllium atom. The nucleus has four protons and four neutrons confined to a small volume of radius 10 -15 m. The two 1 s electrons make a spherical charge cloud at an averagedistance of 1.3 x 10 -11 m from the nucleus, whereas the two 2s electrons make another spherical cloud at an average distance of 5.2 x 10 -11m from the nucleus. Findthe electric field at (a) a point just inside the 1s cloudand (b) a point just inside the 2s cloud.
