I am doing B.Sc. physics hons(1 yr),is it possible to do masters in engineering after my graduation in physics?

There is no provision of allowing B.Sc. degree holders for admission in M.Tech.

You can't get admission in M.Tech. in any college. If you wish to go for M.Tech. after B.Sc. you will have to first pursue an M.Sc. only then you will become eligible to do M.Tech.

Kindly revert for further queries.
