Question
As an object acquires a positive charge its mass will likely
I think the mass will decrease because as the object becomes positive electrons will be lost making it less negative and rather positive. Though electrons do not really have much mass it would make sense that the mass would not change? For an "object" I can't imagine a change in the mass because of charge. THough in a particle it would make sense because the scale is so small?
Particle (a) has mass m and charge +q and is thus attracted to particle (b) with mass 2m and charge -2q. Which particle is more attracted toward the other, and by how much?
I'm thinking the larger particle is more attracted to the smaller particle because it has more surface area to attract the smaller particle and because the larger particle is twice as negatively charged so it would be twice as attracted to the positive charge?? So maybe c or d?
THANKS!!!!
increaseExplanation / Answer
In the first let us say a particle attains one coulumb charge , then it must loose around 10^ 19 elections . Each electron mass is around 10^ -31 kg , so loss of mass is around 10^-6micrograms Which is very less but is important for many calculation purpose. Hence there will be a reduction in mass . Hence option 2
Second case . Newton's second law is applicable . When two charged bodies are attracted or repelled because of charges on them they experience the same force towards or away from one another . F is same for both the particles . But if one is lighter than the other ,then the acceleration of both will be different that is if heavy mass experiences same force as the lighter mass then the heavier mass will have less acceleration F = ma . So heavy mass will move slower than the lighter mass but both the mass will experience same force . Hence option 5
