Physics teacher: “The electrical force that repels the bottom of your foot from the surface of the earth is greater than the gravitational attraction between the entire earth and yourself”.

How can they be true?

If it weren’t true you would be experiencing a net acceleration due to the imbalance in the forces acting on you.
What’s really interesting is figuring out WHY mechanistically it’s true. I had to rethink the whole thing this morning, because it really is pretty nuts how much weaker gravity is than the electrostatic force.
