- The diagram shows a block of mass m = 3.50 kg resting on a plane inclined at an angle of 0 = 40° to the horizontal. The coefficient of static friction between the block and the plane is μstatic = 0.30, and the block is stationary but just on the point of sliding down the slope. Ff F₁ 3 mg N 0 The diagram shows the four forces acting on the block: an applied force F₁ acting perpendicular to the slope (in the -y direction), 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 up the slope, opposing the tendency of the block to move down the slope. Find the the minimum magnitude of the applied force F₁ that can be exerted if the block is to remain stationary.

The magnitude of the force on a particle increases as the cube of the distance from that point, that is, F∝ r3, if the distance from the P to the position of the particle is r. It has been determined that the constant of proportionality is 0.23 N/m3, i.e. the magnitude of the force on a particle can be written as 0.23r3, when the particle is at a distance r from the force center. Find the magnitude of the potential energy, in joules, of a particle subjected to this force when the particle is at a distance 0.21 m from point P assuming the potential energy to be zero when the particle is at P.
