The inverse stare law.
😆 nice one
I don’t understand the formula, but I understand Mr. Bean. +1
If you have two charges
q1andq2, you can get the force between themFby multiplying them with the coulomb constantK(approximately 9 × 10^9) and then dividing that by the distance between them squaredr^2.q1andq2cannot be negative. Sometimes you’ll not be given a charge, and instead the problem will tell you that you have a proton or electron, both of them have the same charge (1.6 × 10^-19 C), but electrons have a negative charge.q1 and q2 can be negative. The force is the same as if they were positive because -1 x -1 = 1
In this case yes, but if q1 was -20μC, q2 was 30μC, and r was 0.5m, then using -20μC as it is would make F equal to -21.6N which is just 21.6N of attraction force between the two charges.
If they are oppositely charged particles, I would expect that there is a force of attraction acting on them, yes.
I am not saying that’s wrong, just that there’s 21.6N of attraction force between the two charges not -21.6N.
But those are the same thing.
No, if the force is negative it acts in the opposite direction
But that if both are negative not one pos one neg like the previous commenter gave in their examples, so the true formula has an absolute value in the numerator: |q1Xq2|
No, but there should be a minus in the Coulomb formula
G is a constant,
m is mass,
d is distance from each other starting from their center of mass,
This measures gravitational force, F
Coulomb had the last laugh though because Newton’s theory has been superseded by relativity.
What was you doing step gravity?
-Time, probably
Now that’s just not fair, Coulomb was born way after Newton. At least make Newton a zombie for realism.
Newton: “FagMad!”
Coulumb: “Fuckyouare!”
If there’s anyone who can, please let me know if the similarities between these two formulas imply a relationship between gravity and electrical attraction or hint at a unified theory, or if it’s just a coincidence or a consequence of something else.
The relation between them is that they’re both forces that scale with the inverse square of the distance between the objects. Any force that scales with the inverse square of distance has pretty much the same general form.
Another similarity is that both are incomplete, first approximations that describe their respective forces. The more complete versions are Maxwell’s laws for electromagnetism and General Relativity for gravity.
