Questions 15 and 16 are case study based questions and are compuisory Attempt four sub parts from each question Each question carries 1 mark 15 Electric flux through an area is defined as E A Gauss law is used to assess amount of enclosed charge The concept of flux and Gauss law is very useful as in cases of non planar area calculation of flux is not easy Gauss law is also very important in calculating the electrostatic field Flux due to change is additive in nature Gauss law is not depend on the shape i Gauss law is dependent on internal charge on configuration a No it s not b Yes it depend on chanrge configuration d Both a and b c May be ii Is it necessary condition to have symmetric surface for Gauss law application a Yes b No c May be d Depends on situation iii Electric flux through a closed surface is due to a Total charged enclosed b Total charge present on the surface c Total charge induced charge d All of the above iv The Gaussian surface should not be passed through any discrete charge because a Electric field becomes zero b Electric field remains constant c Electric field due to a system of discrete charge is not well defined at location at any charge
