B. Resuelve los ejercicios (60%)
1. ¿Cuántos electrones se necesitan para
formar una carga de –38 µC, sabiendo que la
carga de un solo electrón es −1.6 X10−19 C?
2. ¿Cuál es la magnitud de la fuerza que ejerce
una carga de 12 µC sobre otra carga de 25
mC si están separadas 28 cm?
3. ¿Cuál es la fuerza eléctrica de repulsión entre
dos protones separados 4.5 X10−15 m uno de
otro en el núcleo atómico? Recuerda que la
carga del protón es la misma que la del
electrón solo que de signo positivo.
