If the photon of the wavelength `150 p m` strikes an atom and one of its inner bound electrons is ejected out with a velocity of `1.5xx10^(7) ms^(-1)`, calculate the energy with which it is bound to the nucleus.

Explanation

To solve the problem, we need to calculate the energy with which the electron is bound to the nucleus (E₀) when a photon strikes the atom and ejects the electron.

### Step-by-Step Solution:

1. **Calculate the Energy of the Photon (E)**:
The energy of a photon can be calculated using the formula:
\[
E = \frac{hc}{\lambda}
