Question

For a particle inside a box of finite potential well, the particle is most stable at what position of x?

(a) x > L

(b) x < 0

(c) 0 < x < L

(d) Not stable in any state

I got this question during a job interview.

This intriguing question comes from Finite Potential Well topic in section Quantum Physics of Engineering Physics I

Answer 1

Correct choice is (c) 0 < x < L

To explain I would say: The particle is most stable when it is inside the box of finite potential well. In that case, the potential energy of the particle is zero.
