A physics teacher explains Gauss's theorem in electrostatics and Gauss's theorem in magnetism to his students in a class. He tells them that total normal electric flux over a closed surface in vacuum is phi_e=(Q)/(in_0) , where Q is algebraic sum of charges inside the surface. Further, total normal magnetic flux over a closed surface in vacuum is always zero. The teacher emphasises that this is because in magnetism, poles always exist in unlike pairs of equal strengh, i.e., isolated magnetic poles called monopoles do not exist. Read the above passage and answer the following questions: (i) What are the implications of Gauss's theorem in magnetism in day to day life? (ii) Two magnetic dipoles of moments 5Am^2 and 3Am^2 oriented along opposite directions are enclosed in a surface. What is total normal magnetic flux over this surface? (iii) Two point charges +4q and -q are enclosed in a surface in vacuum, and third charge 5q lies outside the surface. What is total normal electric flux over the surface?
