Fundamental Forces: Force of one charged particle on another

In summary, the conversation discusses a calculation involving vector components, magnitude, and force. The final result is a force of 64.322, but there is a discrepancy in the y component which needs to be checked.

F=9E9qq/r^2
So first I did the vector stuff.

r2-r1= 1.3 i hat-47.5 j hat-14.5 k hat

magnitude = 49.68

magnitude squared = 2468.19

Now plugging it all in...

F=9E9*6.3E-3*2.8E-3/2468.19=64.322

y vector, -47.5/49.68=-0.956119 j hat

Multiply this by force and I get -61.499 but answer should be -36.14

Thanks. The werid thing is that this I did this question a month ago and made the same exact mistake (my wrong answer is the same as the new wrong answer I just got).
 

1. What are the fundamental forces?

The fundamental forces are the four fundamental interactions that govern the behavior of matter and energy in the universe: gravity, electromagnetism, strong nuclear force, and weak nuclear force.

2. How does the force of one charged particle on another work?

The force of one charged particle on another is a result of the interaction between their electric fields. Like charges repel each other, while opposite charges attract each other.

3. What is the equation for calculating the force of one charged particle on another?

The equation for calculating the force of one charged particle on another is F = k * (q1 * q2) / r^2, where k is the Coulomb constant, q1 and q2 are the charges of the particles, and r is the distance between them.

4. How does the force of one charged particle on another change with distance?

The force of one charged particle on another decreases as the distance between them increases. This is known as the inverse square law, meaning that the force is inversely proportional to the square of the distance between the particles.

5. What is the role of fundamental forces in the structure of matter?

Fundamental forces play a crucial role in the structure of matter. They are responsible for holding atoms together, forming molecules, and creating the various structures and interactions that make up our physical world.
