NCERT EXAMPLE 12.1 PHYSICS CLASS 12, IIT JEE, NEET

In the Rutherford’s nuclear model of the atom, the
nucleus (radius about 10–15 m) is analogous to the sun about which
the electron move in orbit (radius 10–10 m) like the earth orbits
around the sun. If the dimensions of the solar system had the same
proportions as those of the atom, would the earth be closer to or
farther away from the sun than actually it is? The radius of earth’s
orbit is about 1.5 ¥ 1011 m. The radius of sun is taken as 7 ¥ 108 m.
