Question

What is thE Rquation fo calculating the electrical force between two charges?

Answer 1

The direction of the electrical force is dependent upon whether the charged objects are charged with like charge or opposite charge and upon their spatial orientation. By knowing the type of charge on the two objects, the direction of the force on either one of them can be determined with a little reasoning.

Answer 2

The equation for calculating the electrical force between the two charges is given by Coulomb's law

F=\frac{k q1 q2}{r^{2}}

K=constant= 9 x 10⁹ N m²/C²

q1= charge on first particle

q2= charge on second particle

r= distance between the two charges

Greater is the magnitude of the charges, greater will be the force between the two charges. The force is inversely proportional to the square of the distance between the charges.
