The total potential energy as a function of displacement u is sketched in Fig. 8.6.1. With reference to the figure, Eqn. 8.6.2 can be interpreted as follows: the total potential energy attains a stationary value (maximum or minimum) at the actual displacement (u1); for example, 0 for an incorrect displacement u2. Thus the solution for displacement

For a simple harmonic motion between A and B, with O as the mean position, maximum kinetic energy of the particle executing SHM will be at O and maximum potential energy will be at A and B.∴ Displacement between maximum potential energy and maximum kinetic energy is ± a.
Here in the figure at point A potential energy is decreasing, So kinetic energy is increasing. So, Force at A is +Ve. And At Point B potential energy is increasing, So kinetic energy is decreasing. So, Force at A will be -Ve. To move the object more force is required and making object move less force is required. Answer (B) Positive, Negative.

Potential Energy is defined as the stored energy possessed by a system as a result of the relative positions of the components of that system. For example, if a ball is held above the ground, the system comprising the ball and the earth has a certain amount of potential energy; lifting the ball higher increases the amount of potential energy the system possesses.

The barrier is higher than 0 Joules, which is the maximal value of potential energy the particle can have at any part of its trajectory. So the particle will remain either in the left of right part of that double well and doesn't cross the barrier.
