Cheropanov's mistake is that the '1's have dimension. That dimension cancels out the dimension of r. What is left is the charge squared term. He is wrong about the lower case f. It is a constant and must have units to cancel out the charge squared… -

I just double checked and Coulombs law you mentioned does in fact pass dimensional analysis, not surprisingly.
The constant ke is called the Coulomb constant and is equal to 1/4πε0, where ε0 is the electric constant; ke ≈ 8.988×109 N⋅m2⋅C−2
The m^2 in ke…
