For question number 6 two statements are given- one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below: a) Both A and R are true and R is correct explanation of the assertion. b) Both A and R are true but R is not the correct explanation of the assertion. c) A is true but R is false. d) A is false but R is true.
i) Assertion: Cathode rays consists of negatively charged particles, these are attracted towards anode (+ve terminal). Reason: Anode rays (canal rays) consists of positively charged particles and these are attracted towards cathode (-ve terminal). ii) Assertion (A): An anion has more electrons than the neutral atom. Reason (R): Anion is formed due to loss of electrons. iii) Assertion (A): Dust particles in air form aerosol. Reason (R): Dust particles form dispersion medium and air is dispersed phase.
‘A’ has 9 protons, 9 electrons and 10 neutrons. ‘B’ had 12 protons, 12 electrons and 12 neutrons. Formula between A and B is: a) BA2 b) AB2 c) B2A3 d) AB4
