Homework Help: Seperation of the induced charge

1. The problem statement, all variables and given/known data

Please look in to the attached file. In that you can see a block conductor is moving within the magnetic field which is acting isto the page. What will be the seperation of the induced charge? will it be 1 or 2?

2. Relevant equations



3. The attempt at a solution
By using the right hand rule the direction of current was found and it was from right to left.
So i thought that the right side become positively charged left side would have negative charge but the answer was the 1. why?
Help me please

 

ooohhhh!! I got it know
Thanks a lot!!!
