A particle free to move along the x-axis has potential energy given by U(x) = k[1−exp(−x^2 )] for−∞≤ x ≤+∞, where k is a positive constant of appropriate dimensions. Then: A particle free to move along the x-axis has potential energy given by U(x) = k[1−exp(−x^2 )] for−∞≤ x ≤+∞ where k is a positive [...]
