Each atom of iron will have a net positive charge `26xx0.01xx1.6xx10^-19`C on it in the assumed world. The total positive charge on a 1 kg block would be
(6xx10^26)/58xx26xx1.6xx10^(-10)C`
`=4.3 XX10^5c`
The Coulomb force between the two blocks is
`=1/(4piepsilon_0) (q_1 q_2)/r^2= (9.0xx10^9 N-m^2/C^2xx(4.3xx10^5C)^2)/(1 m)^2)
`=1.7xx10^21N`.
A tremendous force indeed!
