The kinetic energy of an electron accelerated through a potential difference of 100V is

A

`1.6 xx 10^(21)J`

B

`1.6 xx 10^(-29)J`

C

`1.6 xx 10^(-17)J`

D

`1.6 xx 10^(-34)J`

Text Solution

Verified by Experts

The correct Answer is:
C
Given, V= 100 V and q= e= `1.6 xx 10^(-19)J`
As, `W= qV = 1.6 xx 10^(-19)xx 100`
So, kinetic energy KE= W= `1.6 xx 10^(-17)J`
