Question

Given two charges, pick the answers that are true : The two charges act on one another no matter how far apart they are, all the way to infinity
If charge "A" is attracted to "B", then charge "B" is repelled from "A"
Plus and plus repel
If charge "A" is attracted to "B", then charge "B" is equally attracted to "A"
Minus and minus repel
Plus and minus attract

Answer 1

Answer:

All true except the second one.

Explanation:

The two charges act on one another no matter how far apart they are, all the way to infinity . True. Coulomb law doesn't have a distance limitation.

If charge "A" is attracted to "B", then charge "B" is repelled from "A" . False. This violates Newton 3rd Law (Action-Reaction)

Plus and plus repel . True . Charges of same sign repel and opposite sign atract.

If charge "A" is attracted to "B", then charge "B" is equally attracted to "A" . True. This is Newton 3rd Law (Action-Reaction)

Minus and minus repel . True . Charges of same sign repel and opposite sign atract.

Plus and minus attract . True . Charges of same sign repel and opposite sign atract.
