Teaching MPPSC Assistant Professor Mock Test Series 2025 Chemical Sciences Basic Principles of Quantum Mechanics Particle-in-a-box
A particle is in a one-dimensional box with a potential V0 inside the box and infinite outside. An energy state corresponding to n = 0 (n: quantum number) is not allowed because
1
the total energy becomes zero
2
the average momentum becomes zero
3
the wave function becomes zero everywhere
4
the potential V0 ≠ 0
