The kinetic energy of an electron, which is accelerated in the potential difference of 100 V , is

Options

  1. A1.6×10−17 J1.6 \times 10^{-17} \mathrm{~J}
  2. B1.6×10−14 J1.6 \times 10^{-14} \mathrm{~J}
  3. C1.6×10−10 J1.6 \times 10^{-10} \mathrm{~J}
  4. D1.6×10−8 J1.6 \times 10^{-8} \mathrm{~J}

Correct answer

A. 1.6×10−17 J1.6 \times 10^{-17} \mathrm{~J}

Step-by-step solution

KE=eV=1.6×10−19×100=1.6×10−17 J\mathrm{KE}=e V=1.6 \times 10^{-19} \times 100=1.6 \times 10^{-17} \mathrm{~J}
