Question

Find the electric force between two electrons separated by a distance of 10 cm.(The charge of an electron=-1.6x10^-19 C

Answer 1

Answer

the electric force between two electrons separated by a distance of 10 cm is given by

$F=\frac{kqq'}{r^2}\\=\frac{9*10^9*1.6*1.6*10^{-38}}{0.1*0.1}\\=23.04*10^{-27}N$
