How does the amount, or magnitude, of charge on an object affect its attraction or repulsion of another object? also just keep this one explained but maybe a two

The magnitude of an object's charge can either increase or decrease the attraction/ repulsion between another object. The larger the difference of the two object's charges, the stronger opposite charges attract, and the stronger like charges repel.

Iwas in a argument about a certain class grade with my teacher. it was a ‘a-’when i felt that i deserved a ‘a’. i showed him (my teacher) why i felt i derserved so. i questioned what i got wrong and showed him what i learned. i look back to that teacher with nothing but love and support because that’s the class that i actually learned the most. the moral of the story is to see where the other person is coming from and what they have done. also, when in a conflict, never attack the persons character. this will just make the argument end poorly.
