Find approximately the third cosmic velocity v_3 , i.e. the minimum velocity that has to be imparted to a body relative to the Earth's surface to drive it out of the Solar system. The rotation of the Earth about its own axis is to be neglected.

In Rutherford's nuclear model of the atom, the nucleus (radius about 10^(-15)m ) is analogous to the sum about which the electron moves in orbit (radius about 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 further away form the sun than actually it is ? The radius of earth's orbit is about is 1.5xx10^(11)m . The radius of the sun is taken as 7xx10^8m .
