Hello Ram,

Since you have not mentioned your category, I am going to assume general, according to this year's cut offs by allahabad university, with 110 marks in M.Sc physics, it would be unlikely you will be able to get admission in main campus. It's cutoff is 160 marks and above for general category.

Hope this helps.
