- In a 1911 paper, Ernest Rutherford said: In order to form some idea of the forces required to deflect an alpha particle through a large angle, consider an atom containing a point positive charge Ze at its center and surrounded by a distribution of negative electricity, – Ze uniformly distributed within a sphere of radius R. Derive an expression for the magnitude of the electric field at the center of the atom. - Express your answer using the parameters +Ze and -Ze.arrow_forwardClassify the following as either a fermion or a boson: (a) an electron. (b) a proton. (c) a neutron. and (d) a photon.arrow_forwardIn regard to the greenhouse effect, which statement is not true? (a) Ultraviolet and visible radiation are converted to infrared radiation at the surface of Earth. (b) Approximately one-third of the radiation of the Sun does not enter the atmosphere of Earth. (c) Infrared radiation is absorbed by greenhouse gases. (d) Greenhouse gases were not historically present in the atmosphere. (e) Ultraviolet radiation is absorbed by ozone.arrow_forward
