Answer:

The probability density function is 0.25\times 10^{8} m^{- 1}

Solution:

Position of the particle in the box, S = 10^{- 10} m

Length of the box, L = 20\times 10^{- 10} m

Now, the probablity is given by:

P = \frac{10^{- 10}}{20\times 10^{- 10}} = \frac{1}{20}

Now,

The probability density, \psi = \frac{P}{L}

\psi = \frac{\frac{1}{20}}{20\times 10^{- 10}} = 0.25\times 10^{8} m^{- 1}
