Coulomb's Law

Coulomb's Law

1. Is

   • As distance increases, the forces and electric fields decrease.The force between the objects can be positive or negative depending on whether the objects are attracted to each other or repelled.

2. States

   • The magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

3. Formula

   • F=kq1q2/r2
     • Bonus
       • constant
         • k
           • is called
             • The electrostatic constant
               • ke = 8.99×109 N m2 C−2
       • "F" is the resulting force between the two charges.
         • The distance between the two charges is "r." The "r" actually stands for "radius of separation" but you just need to know it is a distance.
           • The "q1" and "q2" are values for the amount of charge in each of the particles.
