KENDRIYA VIDYALAYA ARC DOOMDOOMA PHYSICS (THEORY) CLASS: XII Time allowed: 3 hrs Max.Marks:70 General Instructions: (a) All questions are compulsory (b) There are 37 questions in total. Qns. 1 to 20 carry 1 mark each. Qns. 21 to 27 carry 2 marks each, Qns. 28 to 34 carry 3 mark each and Qns. 35 to 37 carry 5 marks each. (c) There is no overall choice. However, an internal choice has been provided in one question of 2 marks, one question of 3 marks and all three questions of 5 marks each. You have to attempt only one of the given choices in such questions. (d) Use of calculators is not permitted. (e) You may use the following physical constants wherever necessary. c = 3 x 108 m s-1 h = 6.6 x 10-34 J s e = 1.6 x 10-19C o = 4 x 10-7 T m A-1 1/4 o = 9 x 109 N m2C-2 Avogadro number NA = 6.023 x 1023 mol-1 Mass of the neutron = 1.675 x 10-27 kg Boltzmann constant, k = 1.38 x 1023 J K-1 ______________________________________________________________________________________________________ 1. The electrostatic force between two charges Q1 and Q2 at separation r is given by F= K.Q1Q2 r2 . The constant K 1) 2) 3) 4) depends on the system of units only depends on the medium between the charges only depends on both the medium between the charges and the system of units is independent of both the system of units and the medium between the charges 2. On the perpendicular bisector of an electric dipole, the electric intensity E and potential V are 1) E,V both are equal to Zero 2) E and V both are not equal to Zero 3) V = 0 but E is not equal to Zero 4) E=0 but V is not equal to Zero
