# Electric Field and Force Calculation in an Equilateral Triangle

## How can we calculate the electric field at the position of charge q due to other charged particles in an equilateral triangle?

We have three charged particles at the corners of an equilateral triangle with given values for charges and length. How can we determine the electric field at the position of charge q?

## Electric Field Calculation:

The electric field at the position of charge q due to the other charges can be calculated using the formula E = (1/4πε₀) × [(q1/r₁²) + (q2/r₂²)].

To calculate the electric field at the position of charge q, we first find the electric field due to each individual charge at point q. The electric field due to each charge is calculated based on the magnitude of the charge and the distance from point q.

The electric field due to charge 1 at point q is determined to be 1.59 kN/C (upward in the i direction), while the electric field due to charge 2 at point q is calculated to be 907 N/C (downward in the i direction).

By adding both electric fields, we arrive at the total electric field at point q, which is 0.68 kN/C.

Therefore, the electric field at the position of charge q due to the other charges in the equilateral triangle is found to be 0.68 kN/C.
