Dear Shri Ghosh
I am not sure what exactly is followed in our institute on your query. To my understanding it depends on your number of Objective that you are working on. Generally accepted style sheet is 12 size Times New Roman with 1.5 space, sometimes 2.0 space with adjusted margins for left and right alignment for use of binding and for bottom space for notes and the references. On your Chapterization query, usually researchers are tuned to this: Ch:1 - Introduction which has all that is contained in your research proposal, followed by objectives as 2 or 3 core chapters, 4rthly summing up and 5thly Findings/Suggestions
This above narration is only for discussion. Most suggestible is, you have to sit with your Research Guide and finalize your query.
