Dear Pradnya,

If you want to solve the maximum number of objective questions in one minute then you have to clear the concepts of physics and do practice lots of questions in physics. Then it is possible to solve the maximum number of objective questions in few minutes. If you are preparing for  NEET or JEE MAIN entrance exam then  I would recommend you some following books like

• Concept of Physics part-1 and 2 by HC Verma
• Objective Physics for NEET Vol.1 and 2 by DC Pandey
• IE Irodov

To know about JEE Mains and NEET entrance exam :-

• JEE Main 2021 - Latest News, Answer Key, Paper Analysis, Result, Syllabus, Pattern, Admit Card (careers360.com)
• NEET 2021: Exam Date (Sept 12), Registration (Released), nta.ac.in Updates, Website, Syllabus (careers360.com)

Hope it helps...

Best of luck :)
