What is formula for distance of closest approach?

=”EN-US. Answer : The distance of the closest approach is defined as the minimum distance of the charged particle from the nucleus at which initial kinetic energy is the same to the potential energy of the nucleus. This distance (r) isknown as distance of closest approach.

What is the distance of closest approach when a 5Mev Proton approaches a gold nucleus Z 79?

find distance of closest approach when 5Mev proton approaches a gold nucleus(Z=79) the answer is 2 3X10^-14 – Physics – Atoms – 4000187 | Meritnation.com.

What happens to a positively charged particle when it goes near the nucleus of an atom?

A proton is a positively charged particle located in the nucleus of an atom. If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion.

What is the significance of distance of closest approach of alpha particle to atomic number?

When alpha particles reaches to nucleus: When the alpha particle reaches the closest distance of approach, its total kinetic energy will be converted into the potential energy of the system.

What do you mean by distance of closest approach & also write the formula with proper symbols explanations?

Distance of closest approach (rc) is given by. (rc) is inversely proportional to K. Thus, ‘K’ is doubled therefore rc becomes r/2.

What is distance of closest approach in α scattering experiment?

Distance of closest approach is of the order of 10−14 m. At the distance of closest approach, the kinetic energy of the α− particle is transformed into electrostatic potential.

What would be the distance of closest approach when an alpha particle of kinetic energy 5.5 MeV is bombarded to a gold nucleus atomic number of Au 79?

6×10-19)]/5.5×10-13 = 6.6×10-14 m.

What is the closest distance between the alpha particle and the gold nucleus in M?

The distance of closest approach of an alpha particle to the nucleus of gold is 2.73×10-14 m.

How do a neutron and a proton compare?

Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).

What is the formula of distance of closest approach of an alpha-particle?

If the momentum of the alpha-particle is 2p, the corresponding distance of closest approach is (1) 4r (2) 2r (3) 2/r (4) r/4. All of the kinetic energy of incident particles is converted to the potential energy of the system at the distance of closest approach.

What is distance of closest approach of an α particle?

\[{{r}_{0}}\]= distance of closest approach of the \[\alpha \] particle to the nucleus. Therefore, the distance of closest approach is \[41.2fm\].
