Response:
Some details are lacking in the question; here’s the complete version: A -3.0 nC point charge is positioned at the origin, while a -5.0 nC point charge exists along the x-axis at x = 0.800 m. Determine the overall electric force that the two charges would have on an electron situated at 0.200 m along the x-axis.
Clarification:
Coulomb's law applies to solve this problem as illustrated in the accompanying file.

Para calcular el peso utilizamos la fórmula:
Cuando tenemos dos cuerpos, empleamos la fórmula de la gravedad general:
Donde:
G = constante de gravedad =
Mp = masa de la persona = 882 / 9.81= 89.9kg
ME = masa de la Tierra =
r = distancia entre la Tierra y la persona
A partir de estas dos fórmulas, deducimos que los lados izquierdos son equivalentes, por lo tanto, los lados derechos también deben serlo.
Resolviendo esta ecuación para r:
r=6371116m = 6371.116km
Esta es la distancia desde el centro de la Tierra. El radio de la Tierra es 6370km y la altura sobre la superficie es 6371.116 - 6370 = 1.116km o 1116m.
