Question

With what velocity should an alpha particle travel towards the nucleus of a Copper atom so as to arrive at a distance 10^-13 m from the nucleus of the Copper atom

Answer 1

Answer:

The velocity at which the α−particle travel towards the nucleus of a Cu atom to reach at a distance of 10−13m is 6.3×106msec−1. From the nucleus to reach the distance r, the kinetic energy of the alpha particle must be equal to the potential energy of interaction of the alpha particle with the nucleus of copper
