Homework Help: physics please help??

Posted by henry on Saturday, October 27, 2012 at 3:46pm.

I know how to do this problem, but I am having a difficult time figuring out the distance . I thought that from wire 1 to P2 the distance is 45 cm, and the distance from wire 2 to the p2 the distance is 35 cm. However, I believe I am wrong, can someone please explain o me where my mistake it .
Question: Two long, straight parallel wires are 10.0 cm apart and carry 3.80 A currents in the same direction. Find the magnitude of the magnetic field at point P2 , 35.0cm to the right of P1.
