हिन्दीGiven below are statements about the sub-atomic particles and atomic models: (A) Cathode rays are deflected by electric and magnetic fields in a manner similar to negatively charged particles. (B) The specific charge of cathode ray particles depends on the material of electrodes used. (C) Millikan determined the charge on an electron using the oil drop method. (D) Rutherford's alpha scattering experiment showed that most of the space in an atom is empty. Which of the above statements are correct?
Correct answer · Option 1
(A), (C) and (D) only
Explanation
Statement (B) is incorrect because cathode ray specific charge does NOT depend on electrode material or gas. (A), (C), and (D) are correct.
