Particle A has a mass of 2 and a charge of -1. Particle B has a mass of 2 and a charge of +1. Are particle A and B necessarily antiparticles? Explain your answer. I don't think so, but I'm not sure how I can explain why.

I tried doing that; can you please explain. Wait, so, would the first velocity be mgh=1/2mv^2 and then I take away the m's?

Also, I think I've found the first velocity, but would I disregard that when finding the velocity at point B?
