Moving wires in magnetic field/force

1. The problem statement, all variables and given/known data
A long straight wire 1 lies along the x-axis. A long straight wire 2 lies along the y-axis so as
to pass very near, but not quite touch wire 1 at the origin. If both wires are free to move, what happens when currents are sent simultaneously in the +x direction through wire 1 and in the +y direction through wire 2? Note that “clockwise around origin” refers to an observer looking down on an xy plane in which +x is to the right and +y upward.

1. Both wires accelerate along the direction of current flow.
2. 1 accelerates in the −y direction, 2 in the -x direction.
3. Both wires rotate counterclockwise around the origin.
4. 1 accelerates in the +y direction, 2 in the -x direction.
5. Neither wire moves.
6. 1 accelerates in the +y direction, 2 in the +x direction.
7. 1 rotates counterclockwise, 2 clockwise around the origin.
8. 1 accelerates in the −y direction, 2 in the +x direction.
9. Both wires rotate clockwise around the origin.
10. 1 rotates clockwise, 2 counterclockwise around the origin.

2. Relevant equations
None


3. The attempt at a solution
I tried using the Right hand rule (#1) to find out the direction of the magnetic field on both wires, then i used the Right hand rule (#2) to find out the direction of the force to find out how it would move. I ended up getting wire 1 moving into the page, which doesn't seem right and is not in one of the answer choices.
 
Nevermind, Solved.
