Massive objects and electric forces

  1. Mar 6, 2009 #1
    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?
