Massive objects and electric forces

Click For Summary
SUMMARY

The discussion centers on the comparative weakness of electric forces in massive bodies, such as humans and planets, versus their gravitational forces. Participants highlight that while subatomic particles like electrons and protons exhibit weak gravitational interactions due to their minuscule masses, the electric force's weakness in larger entities is attributed to their net charge. The Earth has a net charge close to neutral, which explains its inability to levitate humans like a magnet can lift small metallic objects. Understanding these fundamental forces is crucial for grasping the interactions between mass and charge.

PREREQUISITES
  • Basic understanding of electric charge and gravitational force

I can understand why the gravitational force is weak for subatomic particles like the electron and the proton , since they have extremely minuscule masses. I don't understand why the electric force is soo weak for massive bodies, like humans and planets. Why isn't the Earth able to levitate humans beings like an iron magnet is able to lift up small objects?

What is the net charge of the earth? Or a human?
