here is a question:
there is endless wire uniformly charged
and close to it located a wire with
which has 30 degree angle between him and the endless wire,and it charged in uniformed way so that the total charge on it is
the distance of the finite wire and the infinite wire is 0.08 meters
A.find the total force acted on the finite wire.
B.find it when degrees and when degrees.
gaus law for infinite wire i presume its length is l and distance r.
i sum along the finite wire
but the ditance from the infinite changes too.
so it should be a double integral
but its not a 2d body
