A. the pressure decrease
pressure decreases when the surface area over which a force is applied increases. pressure increases when the surface area over which force is applied decreases.
The force per unit length between the two wires is
The magnitude of the force per unit length exerted between two current-carrying wires is given by
where
is the vacuum permeability
are the currents in the two wires
r is the separation between the two wires
For the wires in this problem, we have
r = 2.00 cm = 0.02 m
Substituting into the equation, we find
