Do we hve to consider it as ideal solenoid? I mean magnetic field at centre = u•ni because considering it of finite length of 20cm as given and then finding the angle isnt giving the correct answer

+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.what is your R that you calculated?
solving the que isnt plm i already got the correct answer but by considering it ideal i.e of infinite length and taking B= ůni instead of ůni/ x (cosa+cosb)
we good?
It explicitly mentions near centre you consider uni for such cases
Okay
