356366 Trajectory of an \(\alpha - \) particle in Geiger-Marsden experiment is explained by using
I.
Coulomb’s law II. Newton’s law
III.
Gauss’ law IV. Faraday’s law
Choose the correct option from the codes given below.

1 I and II
2 I and III
3 I and IV
4 I, II and IV
PHXII12:ATOMS

356367 In alpha particle scattering experiment, if \({v}\) is the initial velocity of the particle, then the distance of closest approach is \({d}\). If the velocity is doubled, then the distance of closest approach becomes

1 \({4 d}\)
2 \({2 d}\)
3 \({\dfrac{d}{2}}\)
4 \({\dfrac{d}{4}}\)
PHXII12:ATOMS

356368 The observations of Geiger-Marsden experiment are
I.
Many of \(\alpha - \) particles pass straight through the gold foil
II.
Only about \(0.1\% \) of \(\alpha \) particles scatter by more than \(1^\circ \)
III.
About 1 in 8000 of \(\alpha - \) particles is deflected more than \(90^\circ \)
IV.
Very few \(\alpha - \) particles are reflected back

356369 When an \(\alpha\)-particle happens to come near a nucleus the intense electric field of these scatters it through a large angle then what is the effect of atomic electrons on \(\alpha\)-particle?

1 Repel \(\alpha\)-particle lightly.
2 Deviate \(\alpha\)-particle from their path.
3 Due to the electron cloud it blocks the pathof \(\alpha\)-particle.
4 Do not appreciably effect.
