given,

charge on the electron=1.6×10

i)to find the electrostatic force b/w 2 electron.

let 2 electrons are at a distance 'd' apart

the electrostatic force is F

iii) to show that electrostatic force is much grater then gravitational force.

for this we take ratio

F

=0.0416×10

44

=0.416×10

we can see tham f

ie. electrostatice force is much grater than the gravitational force for 2 electrons separated by a certain distance▄▀▄▀
