MCQ
While doing his experiment, Millikan one day observed the following charges on a single drop
$(i)\  6.563 \times 10^{-19} \mathrm{C}$
$(ii)\ 8.204 \times 10^{-19} \mathrm{C}$
$(iii)\ 11.50 \times 10^{-19} \mathrm{C}$
$(iv)\ 13.13 \times 10^{-19} \mathrm{C}$
$(v)\ 16.48 \times 10^{-19} \mathrm{C}$
$(vi)\ 18.09\times 10^{-19} \mathrm{C}$
From this data the value of the elementary charge $(e)$ was found to be
  • $1.641 \times 10^{-19} \mathrm{C}$
  • B
    $1.630 \times 10^{-19} \mathrm{C}$
  • C
    $1.648 \times 10^{-19} \mathrm{C}$
  • D
    $1.602 \times 10^{-19} \mathrm{C}$

Answer

Correct option: A.
$1.641 \times 10^{-19} \mathrm{C}$
$1.641 \times 10^{-19} \mathrm{C}$
