Concept

Problem: A force parallel to the x-axis acts on a particle moving along the  x-axis. This force is associated with potential energy U(x) given by U(x) = αx4, where αexttip{alpha }{alpha} = 0.710 J/m4.(a) What is the magnitude of the force when the particle is at x = -0.800 m?(b) What is the direction of the force when the particle is at x = -0.800 m?
