A) \[1.60\times {{10}^{-17}}J\]
B) \[1.16\times {{10}^{4}}k\]
C) 418.6 cal
D) \[6.626\times {{10}^{-34}}Ws\]
Correct Answer: A
Solution :
Key Idea: The kinetic energy of electron accelerated through a potential is the product of electron charge and potential difference. Kinetic energy = eV \[=1.6\times {{10}^{-19}}\times 100\] \[=1.6\times {{10}^{-17}}J\]
