Key Idea: The kinetic energy of electron accelerated through a potential is the product of electron charge and potential difference. Kinetic energy = eV =1.6× 10-19× 100 =1.6× 10-17J

Q. The kinetic energy of an accelerated through a potential of 100 V is :

$1.60 \times 10^{- 17} J$

$1.16 \times 10^{4} k$

418.6 cal

$6.626 \times 10^{- 34} W s$

Key Idea: The kinetic energy of electron accelerated through a potential is the product of electron charge and potential difference. Kinetic energy = eV $= 1.6 \times 10^{- 19} \times 100$ $= 1.6 \times 10^{- 17} J$
