The correct explanation is:
The electrical force is much larger than the gravitational force because 10^9 is much greater than 10^–11.
This is because the constants used for calculating electrical force (8.99 × 10^9 N m²/C²) is significantly larger than that for gravitational force (6.67 × 10^–11 N m²/kg²), which indicates that the electrical force is much more substantial compared to the gravitational force.
