`alpha-` particles of `6 MeV` energy is scattered back form a silver foil. Calculate the maximum volume in which the entire positive charge fo the atom is supposed to be concentrated. (`Z` for silver `= 47`)

An alpha -particle of energy 4 Me V is scattered by gold foil (Z = 79) .Calculate the maximum volume in which positive charge of the atom is likely to be concentrated.

An alpha particle of energy 4MeV is scattered through an angle of 180^(@) by a gold foil (Z=79). Calculate the maximum volume in which positive charge of the atom is likely to be concetrated?

Large angle scattering of alpha- particle led Rutherford to the discovery of atomic nucleus. It is the tiny central core of every atom in which entire positive charge of the atom is concentrated. The distance of closet approach of alpha particle from the nucleus is r_(theta)=((Ze)(2e))/(4pi epsilon_(theta)((1)/(2)mv^(2))) This distance r_(theta) gave him the order of size of nucleus. Read the above passage and answer the followign question: (i) What is the distance of closet approach of an alpha particle of energy 7.7 MeV from gold nucleus (z=79)? (ii) What is the implication of this relation in day to day life?

(A) Large angle of Scattering of alpha particles led to the discovery of atomic nucleus (R) : Entire positive charge of atom in concentrated in the central core .

Statement -1 : Large angle scattering of alpha particles led to the discovery of atomic nucleus. Statement -2 : Entire positive charge of atom is concentrated in the central core.

Statement -1 : Large angle scattering of alpha particles led to the discovery of atomic nucleus. Statement -2 : Entire positive charge of atom is concentrated in the central core.

An alpha -particle having kinetic energy of 7.5 MeV is scattered by gold (Z=79) mucleus through 180^(@) . Calculate the distance of closest approach.
