Electrostatics Question 467
Question: An electron (charge = $ 1.6\times {{10}^{-19}} $ coulomb) is accelerated through a potential of 1,00,000 volts. The energy required by the electron is [MP PET 1989]
Options:
A) $ 1.6\times {{10}^{-24}} $ joule
B) $ 1.6\times {{10}^{-14}}erg $
C) $ 0.53\times {{10}^{-14}} $ joule
D) $ 1.6\times {{10}^{-14}} $ joule
Show Answer
Answer:
Correct Answer: D
Solution:
Energy $ =1.6\times {{10}^{-19}}\times 100000=1.6\times {{10}^{-14}}J $
