Question

Consider an electron trapped in an infinite well whose width is 98.5 pm. If it is in a state with n = 15, what are (i) its energy? (ii) the uncertainty in its momentum? (iii) the uncertainty in its position?

Joshi sir comment

Let width=b For nth state nλ2=b λ=2bn Now E =p22m = (hλ)22m Solve after putting the value of λ  Uncertainty in position=b Now use p.x = nh/2π for finding uncertainty in momentum
