Question

Here it is 6 th que and its solution is also given i undstood that q= 3.2×10^-19 C of charge is there in each ion
Then they used the formula q=ne
And n=2 came out ... right that means ion or body has 2 electrons in it that contributed to net charge then how this 2 is the ans of total electrons missing from each but actually n is the number of electrons/protons present in a body

Answer 1

I think you got the question wrong

see

first we found the charge q on the two bodies

for overall neutrality

positive charge+negative charge=0

now we know that the positive charge has to be equal to the negative charge

and thus we found the negative charge by using q=ne,

and we got to know the number of electrons which are deficient.

btw n is the number of excess or deficient electrons in a body.

for ex if u take a simple case

if a neutral body has given 24C of positive charge then how many e are removed?

thus your answer would be:

n*(-e)=-24

n=1.5*10^20

I would recommend u to use NCERT as its a bhagvat gita and would clear all your concepts as its designed by world class teachers and IITians.
