Here, an object of mass m is at the bottom of a hill (A) as shown in the figure. The object is making attempts to cross over both the points B and D in order to go to E against gravity. Consider that the mass is small enough that it undergoes thermal fluctuation. A. What is the chemical potential of the object at B, C and D relative to point A? B. The object tries to escape the barriers with the fundamental attempt frequency is vo. It first hops over the point B to go to C and then from C to hop over the point D in order to go to E. Calculate the rate of escape for the object starting point A to go to E. m A B D C h1h h3 E
