356525 A charged oil drop is moving with a terminal velocity ' \(v_{1}\) ' vertically down wards where a uniform electric field is directed vertically upwards. When it is given some additional charge it moves vertically upwards with terminal velocity ' \(v_{2}\) ' at the same place. In the absence of electric field it falls freely with terminal velocity ' \(v\) '. The ratio of charges (initial to final) is

1 \(\dfrac{v_{1}+v}{v_{2}-v_{1}}\)
2 \(\dfrac{v_{1}+v_{2}}{2 v}\)
3 \(\dfrac{v-v_{1}}{v+v_{2}}\)
4 \(\dfrac{v_{2}-2 v_{1}}{2 v_{1}+v}\)

356526 JJ Thomson's cathode ray tube experiment demonstrated that

1 cathode rays are streams of negatively charged ions
2 all the mass of an atom is essentially in the nucleus
3 the \(e / m\) of electrons is much greater than the \(e / m\) of protons
4 the \(e / m\) ratio of the cathode ray particles changes when a different gas is placed in the discharged tube

356527 In Millikan’s oil drop experiment a drop of charge \(Q\) and radius \(r\) is kept constant between two plates of potential difference of \(800\,V\). Then charge on other drop of radius \(2r\) which is kept constant with a potential difference of \(3200\,V\) is

1 \(2\,Q\)
2 \(\frac{Q}{2}\)
3 \(\frac{Q}{4}\)
4 \(4\,Q\)

356528 According to Sommerfeld, an electron revolves around a nucleus in

1 Irregular path
2 Elliptical orbits
3 Hyperbolic orbits
4 Parabolic

356529 In Thomson's experiment, a magnetic field of induction \({10^{ - 2}}\;Wb{\rm{/}}{m^2}\) is used. For an undeflected beam of cathode rays, a \(p.d.\) of \(500\;V\) is applied between the plates which are \(0.5\;cm\) apart. Then the velocity of the cathode ray beam is (in \(m{\rm{/}}s\)).
