Two blocks with mass m and 2m are placed on a frictionless surface, and m is placed on top of 2m. Given the maximum static friction coefficent between two blocks is u, what is the maximum external force extered on 2m so that two blocks will move with the same acceleration? Please express in u, m and g. Show your work.
