Question

For a box with infinitely hard walls, the potential is maximum at _____________

(a) L

(b) 2L

(c) L/2

(d) 3L

This question was posed to me in my homework.

This interesting question is from Schrodinger Equation (Steady State Form) topic in division Quantum Physics of Engineering Physics I

Answer 1

Correct answer is (a) L

The best explanation: In a box with infinitely high barriers with infinitely hard walls, the potential is infinite when x = 0 and when x = L.
