    Solving an equation involving Coulomb's law

    Thanks Mr. Charles Link. In the first solution i get the q12 -6*10-6q1 -16*10-12 = 0 and for second one i get q12 - 6*10-6q1-16*106 = 0. My question is why i get different powers for the term involving -16.

    Why is charge quantized and unable to exist in fractional or decimal values?

    Homework Statement Quantisation means charge always exist in integral multiples of magnitude of charge of electron and to put it mathematically we say q = ne, where n is an integer 1,2,3,4 ... -1,-2,-3,... etc. Numerous print and web materials say that charge cannot exist in fraction or...

    Attractive nature of nuclear forces

    "At a distance of 1.5 fermi, the nuclear force becomes maximum and remains attractive in nature. However, at a distance of 0.5 fermi, the nuclear force suddenly becomes repulsive. " Revered Members, Nuclear force is a short range force, so naturally when the distance between the nucleons...
