This may not be a challenge for some of you, but it is hard for me as I just got introduced to the topic, your help will be appreciated.
It is about Electric Force. Coulomb's Law.
Charges of -1 micro coulomb and -4 microcoulomb are placed at opposite ends of a meter ruler. Where on the ruler could...
(a) a free electron be placed and be in electrostatic equilibrium?
(b) a free proton be placed and be in electrostatic equilibrium?
F=K(q1q2)/r2
F= Force (Newtons)
Q= Coulombs charges
R= distance between the charges
K= botlzmann constant
I tried getting the answer by doing math without involving phyisics, like this:If 4 microcolombs is 100%
then 1 microcoulomb might be 25%
and I have a 1 meter long ruler,
then the new coulomb would be placed 25% to the right from the force that has 1 microcoulomb. That would be 25 cms to the right from the -1 microcoulomb
I reach this conclusion by math logic, but I believe it's wrong and my teacher told me it really is wrong, my method is ambiguous so..
I hope someone helps me get me the correct answer.
