The diagram shows a block of mass m = 2.50 kg resting on a plane inclined at an angle of
0 = 30° to the horizontal. The coefficient of static friction between the block and the plane
is Ustatic = 0.135, and the block is stationary but just on the point of sliding up the slope.

The diagram shows the four forces acting on the block: an applied force F₁ acting up the
slope, the block's weight mg, the normal reaction force N and the force of static friction,
Ff. In this case, the force of static friction acts down the slope, opposing the tendency of
the block to move up the slope.
Find the the maximum magnitude of the applied force F₁ that can be exerted if the block
is to remain stationary. Specify your answer by entering a number into the empty box
below.
