Dear applicant with 89 percent marks in 10+2 you do have chances of admission into a good private college but in Government Colleges specially when your stream of choice is Physics. There are plenty good colleges in Odisha, but just because you chose to study B.Sc Physics Hons your chances remain low in government Institutes as their minimum marks criteria is more than 92% still do not loose hope and try your best, wait till the final list, in private colleges you have high chances to get Physics. But provided, you have good marks in individual Physics Subject

Hope it helps!!
