What must be the distance charge q1=26x10^-6 C and charge q2=-47x10^-6 C for the electrostatic force between them to have magnitude of 5.70 N?

Question

His requires Coulomb’s law.

Please show work

Answer 1

F = kq₁q₂/d² ⇒

d = √(kq₁q₂/F)

You know q₁, q₂, and F. Look up k in your book, and plug in the numbers. Note that F is negative, since the charges have opposite signs, or you can work this problem with absolute values.
