i want to ask that which book should i prefer for 11 physics

its better to refer 

CONCEPTS OF PHYSICS BY H.C VERMA -1,2

nd if possible NEW PATTERN OF PHYSICS BY ARIHANT publications

Acc. to my opinion you should refer to:

  CONCEPTS OF PHYSICS BY H.C. VERMA for numerical problems

& FUNDAMENTAL OF PHYSICS BY RESNICK/HALLIDAY/WALKER for detailed study of every topic in simplest language(it is available online too)

Dear Shubham,

H. C. Verma is obviously a very good book.. But for more detailed study and to have your concepts enriched you can refer to University Physics by Sears & Zemansky, Halliday & Resnick, Paul A. Tipler, D. Matveev for Optics, Alexender & Sadiku for Electricity and Electromagnetism parts, Kraus, Rizzoni and John Bird for Electricity.. That would be sufficient.. But always try to get the concepts by your style.. Dont limit yourself with the conventions of books or any lecture..

Wishes! 

use the latest edition of halliday/resnick/walker

for class 11 physics it would be better if you buy the the following

• Physics part 1 and part 2
  by rensnick n Halliday(Not walker) published by John Wiley
• Problems in Genral Physics By IE Irodrov and solution also published by CBS Publishers
• Tata McGrwill Hills Physics for IIT
• S Chands ISC Physics is a compiled version good but had many mistakes in the book of 2011th edition (Hope that they might have changed it)
• Iovon s Physics

thats all that i have till date
