Vedclass · Answer

$F _{ y }$ and $F _{ e }$ represent gravitational and electrostatic force respectively between electrons situated at a distance $=0.1\,m$

let, us take the ratio

$\frac{F_e}{F_g}=\frac{1}{4 \pi \epsilon_0} \frac{q^2}{d^2}$

$\frac{m^2}{d^2}$

$\frac{F_e}{F_g}=\frac{1}{4 \pi \epsilon_0} 	imes \frac{1}{G} 	imes \frac{q^2}{ m ^2}$

$\frac{F_e}{F_g}=9 	imes 10^9 	imes \frac{1}{6.67 	imes 10^{-11}} 	imes \frac{\left(1.6 	imes 10^{-19}ight)^2}{\left(9.1 	imes 10^{-31}ight)^2}$

$\Rightarrow \frac{F_e}{F_g}=4.17 	imes 10^{42}$

$	ext { or, } \frac{F_e}{F_g} 	ext { is of the order of } 10^{-42}$
