A proton and an electron are accelerated by the same potential difference, let `lambda_(e)` and `lambda_(p)` denote the de-Broglie wavelengths of the electron and the proton respectively

A

`lambda_(e) = lambda_(p)`

B

`lambda_(e) lt lambda_(p)`

C

`lambda_(e) gt lambda_(p)`

D

The relation between `lambda_(e)` and `lambda_(p)` depends on the accelerating potential difference.
