What is the probability that an electron in the ground state of the hydrogen atom will be found between two spherical shells whose radii are r and `r + Deltar`, (a) if r = 0.500a and `Deltar` = 0.010a and (b) if r = 1.00a and `Deltar` = 0.01a, where a is the Bohr radius? (Hint: `Deltar` is small enough to permit the radial probability density to be taken to be constant between r and `r+ Deltar`.)

Explanation

(a) `3.2xx10^(-3),` (b) `5.4xx10^(-3)`
