In terms of college infrastructure and reputation all the three are very good. But see if you wish to go for Physics then you should be very clear that IIT Bombay or any IIT don't have same kind of placement as that of Engineering. The institute can give you amazing research experience or can give you exposure to foreign university for your research but as Physics is not an industrial course directly you don't expect jobs as Engineering but yeah! its true that there are placements in IIT bombay for different colleges/ coaching institution etc. Although if you can build your coding skills great then you can also expect a good salaried job in IT's.

Now Among CSE and EEE its better to go for CSE because CSE have better offers in terms of packages and park where as most EEE graduates have to work in IT companies as the core jobs are less. Apart from this NIT Warangal have less course fees and the placements in quite good so as per my opinnion CSE will be a better choice.
