I have post it three times, give me the correct answer please (only part c need to do, part a and b was done) The wave function for an electron trapped in a one-dimensional box with impenetrable walls located between x = -2a and x = a is given as

1. Determine A. (ans : ?2/3a)
2. Determine the expectation value of momentum squared, i.e., (p%) for the electron. Express your answer in terms of an and h.(ans: ?^2*pi^2/a^2)
3. Ifa= 1x10-11 m, how much energy is required for exciting the electron to a higher energy state with the quantum number increased by 1? (ans: 4.69*10^-16J)

3. The wave function for an electron trapped in a one-dimensional box with impenetrable walls located between x = -2a and x = a is given as 0, x a a) Determine A. b) Determine the expectation value of momentum squared, i.e., (pi) for the electron. Express your answer in terms of a and h. c) If a = 1x10'\" m, how much energy is required for exciting the electron to a higher energy state with the quantum number increased by l? (25 marks)
