Coulomb

Calculator of the Coulomb Force Between Two Point Charges Located in the XY Plane

x₁ = m
y₁ = m
Q₁ = C
x₂ = m
y₂ = m
Q₂ = C

r is the distance froom the point charge 1 to the point charge 2.
r²= (x₂-x₁)²+(y₂-y₁)² = m² = m²
u is unit vector directed from point charge 1 to point charge 2.
u_x = (x₂-x₁)/|r| = ≈
u_y = (y₂-y₁)/|r| = ≈
F=kQ₁Q₂/r² = N ≈ N
k= 8.9875517923×10⁹ N⋅m²⋅C⁻²
F_x is component X of the force acting to the second charge from the first charge.
F_x=F u_x = N ≈ N
F_y is component Y of the force acting to the second charge from the first charge.
F_y=F u_y = N ≈ N
