Question

Suppose the exact charge neutrality does not hold in a
world and the electron has a charge 1% less in magnitude
than the proton. Calculate the Coulomb force acting
between two blocks of iron each of mass 1 kg separated
by a distance of 1 m. Number of protons in an iron atom
26 and 58 kg of iron contains 6 x 10 atoms.
​

Answer 1

Answer:

Suppose the exact charge neutrality does not hold in a world and the electron has a charge 1% less in magnitude than the proton. ... The number of protons in an iron atom=26 and 58 kg of iron contains 6×1026 atoms. (plz mark me Brainliest) comment me

Answer 2

Answer:

Given two blocks of iron each of mass 1Kg separated by a distance 1m. Number of protons in iron atom =26

58Kg of iron contains 6×10

26

atoms

We have to find Coulomb's Force between two iron blocks.

Also given, electron has a charge 1% less than proton. Since each atom of iron will have a net positive charge 26×0.01×1.6×10

−19

C on it.

Total positive charge on 1Kg block would be

58

6×10

26

×26×1.6×10

=4.3×10
