An electron of a velocity 'x' is found to have a certain wavelength. The velocity to be possessed by the neutron to have half the de Broglie wavelength possessed by electron is:

A

`x//1840`

B

`x//920`

C

`3680 x`

D

`x//3680`

Text Solution

Verified by Experts

The correct Answer is:
B
`(1)/((1)/(2)) = (m_(n) v_(n))/(m_(e).v_(e)), V_(n) = (2xxm_(e) xx v_(3))/(mn)`
