Let's calculate the total charge of M=4.8 g=0.0048 kg of protons.
Each proton has a charge of
, and a mass of 
. So, the number of protons is
And so the total charge of these protons is
So, the neutralize this charge, we must have
electrons such that their total charge is
Since the charge of each electron is
, the number of electrons needed is
which is the same as the number of protons (because proton and electron have same charge magnitude). Since the mass of a single electron is
, the total mass of electrons should be
Each proton has a charge of
So, the neutralize this charge, we must have
Since the charge of each electron is
which is the same as the number of protons (because proton and electron have same charge magnitude). Since the mass of a single electron is
The new force between the charges when the distance become 2d will be F'=4F
<h3>What is electrostatic force?</h3>
When two charged particles are separated by the distance d then the force of attraction or repultion acts on the charged particle depending upon the nature of the charge whether it is positive or negative.
The formula for the electrostatic force is given by
Now if the value of d becomes 2d then the formula will become:
Hence the new force between the charges when the distance become 2d will be F'=4F
