The electric potential energy between two positively charged particles changes when the distance between them is tripled.
When the distance between the particles is tripled:
- The electric potential energy decreases because they are now further apart, and the force of attraction between them diminishes.
- The change in electric potential energy is inversely proportional to the square of the distance. This means that if the distance is tripled, the electric potential energy decreases by a factor of 1/(3)^2 = 1/9.
Therefore, the correct answer is:
OD. Se reduce en un factor de 9. (It decreases by a factor of 9.)
