1.	Suppose the exact charge neutrality does not 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 eachof mass 1 kg separated by a distante of 1m. Number of protons in an iron atom =26 and 58 kg of iron contains `6xx10^28` atoms.
Answer» 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!
