Answer

The huge value of the constant k compared to the small gravitational constant G hints at the fact that the electrical force is very strong compared to the gravitational force.

Work Step by Step

Truth be told, the logic in this question is spurious, though the conclusion is correct. Even though it is true that the electrical force is very strong compared to the gravitational force, the ratio of k to G could be made very small if we redefined the units of charge or mass. However, that would not change the physical fact that the electrical force is very strong compared to the gravitational force.
