The physics of Arindam Banerjee, employee of a medical research

Wrong as always! Arindam never worked in medical research. Wonder where
you got that from and how low you racist and bigoted creeps will stoop
to demean and diminish the divine Arindam.

At the very beginning of the video you can read:

    HTN stands for hypertension. Go figure.
BTW, why do you think working in a medical research lab
would "diminish the divine Arindam" ?
So to his "physics":

Quote of the first few statements:
  "The formula for universal gravitation is well known to be,
   as the force F acting between two masses m and M, parted by
   a distance r from their centres of mass, as F=GmM/r^2, where G
   is the gravitational constant found by experiment. Recently
   the author has updated this formula to F=BnN/r^2 where B is
   a constant, and n and N are the number of protons or electrons
   in the masses m and M. It is obvious that as n and N are proportional
   to m and M, this is essentially the same formula with the difference
   that instead of masses, the new formula involves charges. Thus the
   gravitational force is expressed electrostatically, as a
manifestation
   of electrostatic force. In other words, there is no difference
between
   electrostatic force and gravitational force."

Do you, Bertitaylor, like Arindam, claim that the Sun is exerting
the electrostatic force 3.6e22 N on the Earth?

The gravitational force between Earth and the Sun is 3.6e22 N.

 Ridiculous question seeing that there is gravitational attraction which
is really electrostatic.

Maybe you should read it again?
The Newtonian formula is F=GmM/r²   (1)
Arindam's formula is:    F=BnN/r²   (2)
Where:
  B = G
  n = number of protons and electrons in the mass m
  N = number of protons and electrons in the mass M
That means:
   m = n⋅mₑ + n⋅mₚ     (3)
   M = N⋅mₑ + N⋅mₚ     (4)
  where mₑ is the mass of an electron and mₚ is the mass of a proton.
Inserting (3) and (4) in (2) yields:
  F=BnN/r² ≡ BnN/r²
So the two equations are identical!
Since the number of protons and electrons in is the same,
there is no net electric charge in m. Same with M.
Do you really not understand that there is no electrostatic
force between the two neutral masses m and M ?
Do you still claim:
"there is gravitational attraction which is really electrostatic"?

Quote about the pressure within the Earth:
  "F = G*m*D*pi*4*R/3
   Now when R or the radius of the Earth is zero, which is the case
   when the m is at the centre of the Earth, then F = 0. Now pressure
   is force per unit area, so pressure at the centre of the Earth is
   also zero."

Do you, Bertitaylor, like Arindam, claim that the pressure at
the centre of the Earth is zero?

 Yes da oui si haaN hyaN bilkul zaroor ja with wohls on...

Thanks for a clear answer.
You, like Arindam believe that the pressure within the Earth
is highest right below the surface and is diminishing with depth.
The equation F = G*m*D*pi*4*R/3 is the gravitational force
on a mass m when it is a distance R from the centre of the Earth.
The gravitational force on the mass m at the surface is:
  F = m⋅9.91953 N (we ignore the rotation of the Earth)
Let's consider the following scenario:
We have a 1000 m deep cylindrical hole in the surface of the Earth.
The gravitational force on you standing at the bottom of the hole is:
  F = m⋅9.91790 N
If your mass is 80 kg, your weight will be 0.1244 N less at
the bottom of the hole than on the surface.
So the gravitational force diminish with depth.
Now we fill the hole with water.
The pressure at the surface is 1 atm = 1013.25 hPa
The pressure on you is now 10020 kPa or ca 100 atm.
The pressure increases with depth, as any scuba diver would tell you.
How can you, like Arindam, fail to know this?
If we fill the hole with stone with density 5563 kg/m³
(the average density of the Earth),
the pressure at the bottom of the hole becomes:
  55275 kPa or 556 atm
The pressure at the centre of the Earth is 360 Gpa
3.5 millions atm.
Do you still not understand how idiotic Arindam is when he
claim that the pressure at the centre of the Earth is zero?
