Help!?!? Stuck!

How do the magnitude and charge of the two charged particles in the figure above compare? (Ill post the pic in a sec...)

same magnitude and both have a positive charge
a is positive, b is negative and b has half the magnitude of a
a is positive and b is negative with the same magnitude
same magnitude and both have a negative charge

Can you choose multiple options? It could be that they're equal magnitude and (both positive or both negative)

anonymous · Answer

No, only one... :\

anonymous · Answer

Well it's obvious that they both have equal magnitude (because vectors are the same on both particles), and both have the same charge (because like charges repel). I don't think, however, that you can determine if they're both negative or both positive from the picture. Maybe I'm wrong.

I think it would be A. Because i looked up some pictures of positively charged particles and the arrows are going out of the particle. Since both a and b have the arrows coming out of them, i would think they'd both be positive. So with your reasoning and mine, i think its safe to say that it would be A. Thanks for your help!! :)
