greetings shubham,
following is a typical syllabus of engineering physics:
http://dtu.ac.in/Web/Academics/syllabus.php
if you do it from a top college, you can expect a package of around 6-8 LPA in the beginning.
if you do it from a private college/average college, you may get a package of 3-4 LPA.
hope this helps.
good luck
