Hello Surya.
Congratulations on securing this rank.
Well in engineering you will be getting some or the other application of physics at some point so you can't really expect that you won't be dealing with physics at all in this 4 year course. Streams like Mechanical, Civil, Electrical, Electronics require the major application of Physics mostly so you should not go for these streams.
You can opt for streams like CSE, Biotech, Chemical, Food technology for a reduced application of Physics. As far as scope is concerned, every stream has scope if not in India then abroad and if you are good in your stream, there will be no end to the amount of scope available. I would suggest you to research about these streams and conclude which one interests you more and which according to you has more scope or will yield better opportunity for you. You will be the best judge as it is you who will be dealing with everything at the end of the day.
Also, you can visit https://engineering.careers360.com/articles/tnea-cutoff to get information regarding the cutoffs of different colleges and branches in the previous years and shortlist the ones where you can get admission with your rank. Having said that, I will also say that the cutoffs vary every year depending on the number of candidates, their rank, the number of seats available, etc.

Hope that helped.
All the best!
