With what velocity should as `alpha`- particle travel toward the nucless of a copper atom at a distance of `10^(13)m` from the nucless of the copper atom ?

With what velocity should an alpha - particle travel toward the nucleus of a copper atom at a distance of 10^(-13)m from the nucleus of the copper atom ?

With what velocity should an alpha - particle travel towards the nucleus of a copper atom at a distance of 10^(-13)m from the nucleus of the copper atom?

With what velocity should an alpha paricle towards the nucless of a copper atom so as to errive at a distance 10^(-3)m from the nucless of the copper atom ?

In the Rutherford's experiment, a particles were bombarded towards the copper atoms so as to arrives a distance of 10^(-13) metre from the nucleus of copper and then getting either deflected or traversing back. The a-particles did not move further closer The velocity of the a-particles must be

In the Rutherford's experiment, a particles were bombarded towards the copper atoms so as to arrives a distance of 10^(-13) metre from the nucleus of copper and then getting either deflected or traversing back. The a-particles did not move further closer It can also be concluded that the electrostatic potential energy is equal to

An alpha particle having KE equal to 8.7MeV is projected towards the nucleus of copper with Z=29. Calculate its distance of closest approach.

A 5 MeV alpha particle is projected towards a stationary nucleus of atomic number 40. Calculate distance of closest approach.
