Calculate the uncertainty in the position of the particle

Question

Compute a particle of mass m confined in an infinite one-dimensional potential well of length a. suppose the system is in quantum state n.
1. Calculate the uncertainty in the position of the particle Δx = [Δx²]^1/2 ,as a function of n, m, a, and fundamental constants.
2. Calculate the uncertainty in the momentum of the particle, Δp_x , as a function of n, m, a, and fundamental constants.
