Three long wires all lie in an
xy
plane parallel to the
x
axis. They intersect the
y
axis at the origin,
y=
d
, and
y=2d
, where
d=8.4cm
. The two outer wires each carry a current of
5.6A
in the positive
x
direction. What is the magnitude of the force on a
1.7m
section of either of the outer wires if the current in the center wire is
3.0A(a)
in the positive
x
direction and
(b)
in the negative
x
direction? (a) Number Units (b) Number Units
