Given:

Charge on the i^th particle ,

Distance of i^th particle from origin,

________________________________________________

Formula used:

By Coulomb’s law, the electric force is given by:

Where ϵ₀ is the permittivity of free space

q₁ and q₂ are the magnitude of charges

r is the distance of separation between the charges

__________________________________________________

Magnitude of force on the 1C charge due to i^thparticle is given by:

(Here, q₁ =, and )

Substituting the values, we get

All the forces are in negative-x direction. Hence, we can simply add them up to get the magnitude of net force.
