An electrically charged object will induce an electric field around it. Effect of electric field disuatu point vector quantities expressed by Strong Electric Field (E), with units N / C.
E = k Q / R ²
If an object other uncharged Q 'is placed at the point, then charged objects will experience ELECTROSTATIC FORCE F (also called the Coulomb force).
F = Q E = k Q Q '/ R ²
with F = Tensile / reject (in Newton)
R = distance charge Q and Q '(in meters)
k = constant = ¼ PIO = 9 x 10E9 Nm / coul
Io = permittivity of vacuum = 8.85 x 10E-12 coul ² / Nm
Q, Q '= electric charge (Coulomb)
