    Solutions

  • Question 2/10
    4 / -1
    In Millikan\'s oil drop experiment, an oil drop of mass 16 × 10–6 kg is balanced by an electric field of 106 V/m. The charge in coulomb on the drop, assuming g = 10 m/s2 is
    Solutions

  • Question 3/10
    4 / -1
    Which is not true will respect to the cathode rays?
    Solutions

  • Question 4/10
    4 / -1
    In Thomsons experiment of finding e/m for electrons, beam of electron is replaced by that of muons (particles with same charge as of electrons but mass 208 times that of electrons). No deflection condition in this case is satisfied if

  • Question 8/10
    4 / -1
    In a Thomson set-up for the determination of e/m, electrons accelerated by 2.5 kV enter the region of crossed electric and magnetic fields of strengths 3.6 × 104 Vm–1 and 1.2 × 10–3 T respectively and go through undeflected. The measured value of elm of the electron is equal to
