An unknown nucleus observed it is composed of 2 neutrons and 4 protons. {a} What is the total electric charge of this nucleus? (Recall: Charge of a proton is given by q=+t.6 x10"(-19) C) to} Using the Coulomb's law find the electric eld at a distance of 0.005 cm away from this nucleus. {c} Find the electric field due to this nucleus at the same distance (0.005 cm) using the lE3auss's law. (HINT: Use a Gaussian surface such that the electric field is constant at the same distance in any direction}I NOTE: You should get the same results in (b) and (c). s Add file 3.
