Question

Two long, parallel wires are separated by a distance of 2.80 cm
. The force per unit length that each wire exerts on the other is
3.40×10^{−5} N/m , and the wires repel each other. The
current in one wire is 0.520 A .

a) What is the current in the second wire?

Answer #1

Two long, parallel wires separated by 2.80 cm carry currents in
opposite directions. The current in one wire is 1.30 A, and the
current in the other is 3.35 A.
(a) Find the magnitude of the force per unit length that one
wire exerts on the other.
(b) Is the force attractive or repulsive?

a) Two long, parallel wires are separated by a distance 3.00 cm
and are repelling each other with a force per unit length of
2.00×10−5 Nm−1 . If a current of 0.600 A is
flowing along one wire, what is the current in the other wire? Are
the currents flowing in the same directions or in opposite
directions?
b) Two long, parallel wires are hanging by regularly spaced,
4.00 cm long cords from a common axis. The wires have a...
