## Electric Field
The electric field describes the force per unit charge experienced by a test charge placed near a source charge.
### Formula
**E = k * |Q| / r²**
where k = 8.9875 x 10^9 N·m²/C² is Coulomb's constant. The field points radially outward from positive charges and inward toward negative charges.

Ejemplo Resuelto
Electric field 10 cm from a 1 microcoulomb charge.
- E = k * Q / r²
- E = 8.9875e9 * 1e-6 / 0.01
- E = 8987.5 / 0.01
- E = 898,750 N/C
