Consider a potential energy function as shown here. What does this potential energy function imply? (A) There is a physical wall at x=-a/2 and another one at x=+a/2. (B) A particle can move freely between x = -a/2 and x= +a/2 without any force acting on it. At x = ±a/2, a force will act on a particle, pushing it into region II A, B and C (E) B and C
