PHYSICS 3B Chapter Notes - Chapter 23: Field Line, Test Particle, Electric Field
Document Summary
The magnitude of the electric force between two charges is proportional to the product s qu , and inversely proportional to the distance between them v of the charges . " f = k qi tf r - proportionality constant : k - unit of charge c = coulomb. * f - charges : iwc = to-6 c. Force lk) can be written as eo (permittivity offree space) meter. = 8. 85 no -1204n - m - to = if ,, Direction of the electrical forcer is along the line connecting the charges. Repulsive if they are the same opposite. Electrical force can be written as a vector. R is the distance between the two charges.
