$2$ When two point charges are $2\mathrm{.}0$ cm apart, each one experiences a $\backslash (1\mathrm{.}0-\backslash$mathrm$\{$N$\}\backslash )$ electric force due to the other charge. If they are moved to a new separation of $8\mathrm{.}0$ cm $,$ the electric force on each of them is closest to

$0\mathrm{.}063$ N $.$

$1\mathrm{.}0$ N $.$

$16$ N $.$

$0\mathrm{.}25$ N $.$

$4\mathrm{.}0$ N $.$
