What Happens to the Force on Charged Particles When They Move Apart?

Click For Summary
SUMMARY

When a positive and negative charge are released from proximity, the force between them decreases as they move apart, according to Coulomb's Law. This law states that the force (F) is inversely proportional to the square of the distance (r) between the charges, represented mathematically as F = (1 / (4 π ε₀)) * (q₁ q₂ / r²). As the distance increases, the force diminishes, confirming that the interaction weakens with separation.

When a positive and negative charge are held close to each other and then released, does the force on each particle increase, decrease, or stay the same?
 
Physics news on Phys.org
when you release the particles, what happens?
recall coulombs law:
[tex]\vec{F} = \frac{1} {4 \pi \epsilon_0} \frac{q_1 q_2} {r^2} \hat{r}[/tex]
