Answer 2

It appears that you have provided some variables and units, but it's not clear what you're asking for. Q typically represents charge in coulombs, l1 and l2 appear to be lengths or positions, and B usually represents magnetic field strength in teslas, but your question is not specific.

If you have a specific question or calculation you'd like me to perform using these variables, please provide more context or details, and I'd be happy to help.
