This graph shows the potential energy vs position of a 3.58 kg particle confined to the x-axis. What is the force (in N, magnitude and direction) acting on the particle when it is at x = 11.3 m? Let A = 2 J. Include negative signs as appropriate for the direction. A force that acts in the positive x direction would be considered positive, while a force that acts in the negative x-direction is considered negative.
