Two parallel wires carry equal currents of 10A along the same direction and are seperated by a distance of 2cm.Find the magnetic field at a point which is 2cm away from each of these wires. Plzz answer friends.....3 salutes to a good ans......

got it i think!
B=u/2pi i/a
B=u/2pi 10/(0.02)
2 wires will have two B's at an angle of 120 degrees
so the resultant is root(B^2+B^2+2B^2cos120)

oops!
did a mistake
they will be at 60 degrees
so B=u/2pi 500root(3)

is the answer = (5.root(3) / 0.02) * u / pi Tesla ? just added cos components of fields. sin components cancel out. so 2 * cos component of any one's field.
