1guys this is very difficult to imagine this figure....
if u just try to do so....
u'll find that for two points which r at same distance from the point shown by the dot on the infinite wire the perpendicular component of the of the magnetic field due to both the points will get cancelled.....
and only the horizontal component comes into play......
and we have to integrate it to get the magnetic field.......
since this magnetic field is not constant we have to again integrate it...
but we here have two variables......
thus the integration will be quite difficult....
but the ans will be some finite value of force...
1too dificult to find see we cant integrate it easily under proper limits
to do that we have to see some symmetry and i cant find any symmetry may be im blind but that is it
1is there no specific location of the infinite wire in 2nd question
i mean some distance from some point must be given
112. No force?
I( L x B) = 0 because angle b/w I and B is 0° or 180°?
Just a tukka[4]
12. ) find the force exerted by the infinite wire (represented by dot) ...
on the sqaure loop as well as on the circular loop... in each of the following cases..
1no one trying ??
[3]
comment at least... !!
like....... whether it is at all solvable :P
1chalo bahar ka circle hata dete hai...
phir sochte hai...
uske baad circle laga denge...
for tym being lets assume... bahar wala loop nahi hai... sirf square loop hai...
1btw, i jus thot of such a question...
yeh koi book ki nahi hai .. sry...
main bhi 'till now' clueless hi hun..
not exactly clueless,,, but trying to find some short method...
the force is changing at every point...
