Alpha Particle Scattering and Rutherford’s Nuclear Model of Atom
PHXII12:ATOMS

356343 An \(\alpha - \) particle of energy \(5\,MeV\) is scattered through \(180^\circ \) by gold nucleus. The distance of closest approach is of the order of

1 \({10^{ - 12}}cm\)
2 \({10^{ - 16}}cm\)
3 \({10^{ - 10}}cm\)
4 \({10^{ - 14}}cm\)
PHXII12:ATOMS

356344 The incorrect statement regarding Rutherford’s atomic model is

1 Atom contains nucleus
2 Size of nucleus is very small in comparison to that of atom
3 Nucleus contains about 70 % mass of the atom
4 Electrons revolve round the nucleus with uniform speed
PHXII12:ATOMS

356345 If an \(\alpha \)-particle of mass \(m\), charged \(q\) and velocity \(v\) is incident on a nucleus of charge \(Q\) and mass \(m\), then the distance of closest approach is:

1 \(\frac{{Qq}}{{4\pi {\varepsilon _0}{m^2}}}\)
2 \(\frac{{Qq}}{{2\pi {\varepsilon _0}m{v^2}}}\)
3 \(\frac{{Qqm{v^2}}}{2}\)
4 \(\frac{{Qq}}{{m{v^2}}}\)
PHXII12:ATOMS

356346 Rutherford’s atomic model could account for

1 Stability of atoms
2 Origin of spectra
3 The positively charged central core of an atom
4 Concept of stationary orbits
PHXII12:ATOMS

356347 According to classical theory, the path of electron in Rutherford atomic model is

1 Straight line
2 Spiral
3 Circular
4 Parabolic
