Any body will move on a rough surface if it is able to overcome the force of friction which opposes relative slipping
The max force friction can apply is equal to uN where u is the coefficient of friction and N is the normal rxn force on the body in a dirxn perpendicular to the dirxn in which friction acts.
It is given by R in your illustration.
 
Hence minimum force reqd to move the body should be greater than friction force or greater than uR
