I am not sure about physics, but surely you can combine maths with your humanities subject. If you have economics in your humanities subject then maths as an additional subject can definitely prove to be a boom for you. Knowledge of core mathematics is highly necessary for understanding the advance theorems of Marco-Micro economics. When it comes to the understanding the concept of consumers producer behaviours, price determination, revenue recognition, etc., you must have the knowledge of matrices, differentiation & integration, statistics and probability. These concepts help a lot while having an advanced and realistic knowledge of economics (as a part of humanities). So, in this way, we can relate the subjects of maths and economics. Here, physics may not help you much (since physics is the application of mathematics in the practical world), but it may help you to enhance your mathematical calculation skills. Hope this helps.
Best of luck.

For an engineering student, it is quite tough to go for Masters in Economic as in whole academic period, students study PCM and no economics, but in Master's degree, a student has to get in-depth knowledge in this subject and needs an introduction to economics before joining MA in Economics. As Economics is a complex subject so after a small introduction to an economics student can get some base for the syllabus and understand the syllabus easily. So, it is beneficial to do MA in economics as less engineering student do this and there is a scope in the finance field, industries, and banking & marketing field.
MA in sociology is the study of social relation, social satisfaction, social interaction and culture. So it is quite easy for a B.Tech student to study MA Sociology rather than MA Economics. A student having good knowledge and understanding can easily go through MA in Sociology. It is quite easy to score good marks in Sociology. After doing this, students can go for PhD. or M.Phil degree. Sociology student has a greater chance to qualify civil services exam or one can also apply for UGC-NET or JRE exam.
S, for engineering students, MA in Sociology is quite beneficial.

There are almost 10 colleges in the University of Delhi which offers BA Geography Hons. They are Kirori Mal College (KMC), Miranda House, Dyal Singh College, Kamala Nehru College, Bhagat Singh College (morning), Bhagat Singh College (evening), Shivaji College, Aditi Mahavidyalaya, B R Ambedkar College and Swami Shraddhanand College but we can't judge between them because every college has some pros and cons. In KiroriMal and Miranda college, the cut-off is very high to get admission but in Bhagat Singh, you may find some good faculties for geography. So it all depends on you that on what parameters you compare the colleges. Hope this helps.
Best of luck.
