For what kinetic energy of a proton, will the associated de-Broglie wavelength be 16.5nm? Mass of proton `=1.675xx10^(-27)kg , h=6.63xx10^(-34)Js`

Explanation

To find the kinetic energy of a proton associated with a de-Broglie wavelength of 16.5 nm, we can follow these steps:

### Step 1: Understand the relationship between de-Broglie wavelength and momentum
The de-Broglie wavelength (\( \lambda \)) is given by the formula:
\[ \lambda = \frac{h}{p} \]
where \( h \) is Planck's constant and \( p \) is the momentum of the particle.
