The linear momentum of an electron, initially at rest, accelerated through a potential difference of 100 V is 

A

`9.1 xx10^(-24)`

B

`6.5 xx10^(-24)`

C

`5.4 xx10^(-24)`

D

`1.6 xx10^(-24)`

Text Solution

Verified by Experts

The correct Answer is:
C
`lamda_e= (1.227)/(sqrtV) nmimplies h/P=(1.227xx10^(-9))/(sqrt(100))`
`implies P=(6.6xx10^(-34))/(1.227 xx10^(-10))=5.4 xx10^(-24) "ks ms"^(-1)`
