The Nucleus of Lead-208

question 26

Short Answer

The nucleus of lead-208, The nucleus of lead-208, ,has 82 protons within a sphere of radius 6.34 × 10−<sup>15</sup>.Each electric charge has a value of 1.60 × 10−<sup>19</sup> C.Assuming that the protons create a spherically symmetric distribution of charge,calculate the electric field at the surface of the nucleus.
