Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

see the attached. you will get how symmetric turms cancel out.in figure cos turms will cancel out .

sir can you explain the fig

if we consider one small element on ri8 side just like wo do in solution. same element is here in left side. when we solve the whole problem symmetric turms will cancel out automatically. if you consider only one elements from ri8 side and take bot sin and cosine component . which one is symmetric will cancel out

this solution is little different, u can approach like this also.. only the limit will change...feel free to ask.. best regards
sir what trigonometric functions we should take at on x,y and z axis. i am confused
dear, it's upto you,let u take axis of circular wire to be z- axis .. then the elementary part of wire make e.f at point p makes an angle theta with z-axis.....
so the overall e.f at point p due to circular wire is along z-axis..
so if u take axis of circular wire to be x or y-axis then the same condition apply... if u take z-axis to be axis then circular wire is on x-y plane..
hope u r getting me..
