Question

Assertion :A charged and an uncharged particle each have the same momentum and same de Broglie wavelength. Reason: de Broglie wavelength does not depend upon the charge.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

The relationship between de Broglie wavelength $\left(\lambda \right)$ and the momentum (p) of a photon is given by:
$\lambda =\frac{h}{p}$.
A charged and an uncharged particle each have the same momentum and same de Broglie wavelength because de Broglie wavelength does not depend upon the charge.

So, the answer is option (A).
