Step-by-step explanation
the electrostatic force between two forces is given by:
then, complete the table we need to use this equation
where
k, q1 and q2 are ginven in the table, so
Step 1
Let
so,replace
hence, for tha row
Step 2
now, do the same for the next Fe, so
b)Let
so,replace
hence, for tha row
Step 3
now, do the same for the next Fe, so
c)Let
so,replace
hence, for that row
Step 4
now, do the same for the next Fe, so
c)Let
so,replace
hence, for tha row
Step 5
now, do the same for the next Fe, so
c)Let
so,replace
hence, for that row
Step 6
find the electrostastic force betweeen electrons
let
as the distance is not give, let's use
distance =1
replace in the formula
therefore, the electrostaic force is
I hope this helps you
