A small block with mass m1 rests on a frictionless horizontal tabletop a distance r from a hole in the center of the table. A string tied to the small block passes down through the hole, and a larger block m2 is suspended from the free end of the string. The m1 is set into uniform circular motion with radius r and speed v. What must v be if m2 is to remain motionless?
