The weight of block B is P=2kN, and the weight of block A is Q=5kN. A horizontal force F is applied to B. As shown in the figure, when the rope of A and the horizontal form an angle of θ=30°, the static sliding friction coefficient between B and the horizontal plane is fs1=0.2, the static sliding friction coefficient between the block A and B fs2=0.25, the minimum value of the horizontal force F required to pull out the block B is ________. A、2.65kN B、2.366kN C、1.4kN D、1.5kN
