Hi there.
00:01
So for this problem, we suppose that one milligram of hydrogen is separated into electrons and protons.
00:14
So we need to suppose also that the protons are placed at the earth north pole and the electrons are placed at the south pole.
00:22
So for this problem, we are asked, what is the resulting compressional force on the earth? in this case, we know that the mass given is one gram.
00:43
One gram, yes, one gram of the mass is one gram of hydrogen.
00:53
And from this we can obtain the number of electrons or protons, because we know that that is going to be the number of electrons and protons is going to be 2 times 1 over 2, and this times the apocratus number, which is equal to 6 .023 times 10 to the 23.
01:26
So from this we obtain a number of electrons and protons of 6 .023 times 10 to the minus 23.
01:38
So with that said, we can obtain the magnitude of charge on north or south bolt because that number of charge, that charge is going to be the value that we obtain for n times the charge of an electron because we know that the charge of an electron is the same as the charge of a proton, but with different sign.
01:59
And then in this case, we're going to have that this is 6 .023 times 10 to the 23.
02:05
And this times a charge of an electron that we know is 1 .6 times 10 to the minus 19.
02:12
So from this we obtain a charge that is equal to 90.
02:24
96 ,000, 6 ,38 columns.
02:35
So with this, we can obtain the force between the pole, the source, the north pole and the south pole because that is going to be the columns constant times the charge squared divided by the separation distance between these two...
