Problems in Physics II for IIT JEE Vol 2 IITJEE main advanced standard 12 XII Shashi Bhusan Tiwari

Problem solving is moving towards a target when the path is not known. If you know the path for sure then it is not a ‘problem’. Therefore, there is no single strategy or path for solving all problems. Despite this fact, to develop a clear path, we need proper visualisation of the given situation in every problem. Therefore, it is recommended that students should always make a neat diagram wherever possible and jot down all necessary information. Then think about the applicable principles and relevant links between them. This will help you to get organised. Remember, practice will not make you perfect; only organised practice will make you perfect. You must know why you are doing a set of calculations or why you are writing an equation. Please don’t panic in any situation. Read the problem again – understand it word by word. Every word is important. You need to focus on key words such as massless, uniform, steady, constant, horizontal, vertical, etc. This will help you in constructing the problem quickly and finalising the relevant principles. If a solution is getting lengthy but you are confident of your approach, just keep going Many problems are tough only because of their mathematical rigour. Always make a habit of checking the units and dimensions of your answers or expressions that look odd. Checking the answers for extreme cases is must. It gives valuable insights and confidence about correctness of the solution.
