Impending state of mation is a critical border line between static and dynamic states of a body A block of mass m is supported on a rough vertical wall by applying a rough vertical wall by appying a force F as shwon in figure coefficent of static fricition between block and wall is `mu` The block under the influenace  F sin`theta` may have a tendency to move upwart or it may be assumed that F `sin theta` justprevents downward fall of th block read the above prevents downward fall of the block .Read the above passage carefully and answer the following quesstions.img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/MPP_PHY_C04_E01_154_Q01.png" width="80%"the value of F for which friction force between the block and the wall is zero
