Question 1 When you stand on a floor the electrons surround your shoes and the floor. What is the force that prevents you from falling through a floor?

a) atomic direction

b) potential energy

c) atomic speed

d) electrical repulsion

d) electrical repulsion

Explanation:

When you stand on a floor, the two different bodies i.e your shoes and the floor on which you stand, are in a very close contact, the electrons that surround your shoes and that of the floor exert a repulsive force on each other, also known as Coulomb's force of repulsion or  electrical repulsive force.

This electrical repulsive force prevents you from falling through the floor.
