Assertion (A) : If the potential difference applied to an electron is made `4` time , the de Broglie wavelength associated is halved
Reason (R ) : On making potential difference `4` times , velocity is doubled and hence `lambda` is halved

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false

D

If assertion is false but reason is true.
