I stopped drinking at 2 am . Had about 6 beers.I got a urine drug test from probation around 11:30 am.Would the test come back positive?

Most likely yes, it will come back positive.

I weight about 110. I drank 6-7 bottles of 12oz's of beer. How many hours would it take to clear my urine?

That depends on the time over which you consumed the beer and your metabolism and the test used for analyzing. Standard lab tests will detect the presence of ethanol in urine across a few hours. However, tests for ethyl glucuronide (EtG), a metabolite of ethanol, are effective for anywhere from 1-1/2 to 4-1/2 days.

Yes, you will test posititive with that little of time
