If electron are accelerated from rest through a potential difference of 10kv, what is the wavelength of the associated electron
[m = 9.1 x 10-31kg, e = 1.6 x 10-19C, h = 6.6 x 10-34js]
[m = 9.1 x 10-31kg, e = 1.6 x 10-19C, h = 6.6 x 10-34js]

Correct Answer: Option A
Explanation:
1.223 x 10-11m
| √(2evm) |
| √(2 x 1.6x10-19 x 10000 x 9.1x10-34) |
1.223 x 10-11m
