If there is an electric force of 5 newtons between two charged particles (q1 = +10 C and q2 = +10 C), how far apart are the particles?

Using the Coulumb law,

Force (electric) = [k Q1 Q2] / d², "d" is "how far apart are the particles"...

F = 5 N 

Q1 = 10 C 

Q2 = 10 C 

5 = k(10)² / d² 

5d² = 100k
d² = 20k 

k is the Coulomb's constant : 910^9 Nm²/C²

d² = 20(910^9)
d² = 1810^10 

d = 4.2*10^5 m or 420 km
