A block of mass 2.00 kg is pushed up against a wall by a force p vector that makes a 50.0° angle with the horizontal as shown below. The coefficient of static friction between the block and the wall is 0.283.

Determine the possible values for the magnitude of p vector that allow the block to remain stationary.

Pmax vector = ?

Pmin vector = ?

I have drawn a FBD to this problem. The mass is in the middle. Branching up is the normal force and branching 50 degrees above the horizontal is P. Branching down is the Force friction and the Weight of the Mass

Summing the forces, I get Psin50-20 (Force weight)-5.66 (Force friction) = 0 and Pmax = 33.497 N. I have tried many ways, but I simply cannot get Pmin. What am I supposed to do? Am I supposed to use Pmax to find Pmin?
