I've recently been learning about basic Electricity, and I just started learning about Electric Fields. I came across this problem yesterday, and the solution has been confusing me ever since.
At first glance, my strategy to solve this problem would simply be applying Newton's Second Law to set the Electrostatic Force equal to
F_e = ma). Then, I would substitute
F_e and plug in the appropriate values to calculate
However, this solution seems to involve using centripetal acceleration to solve the problem, setting
F_c = ma_c. This confuses me because I don't see any way that the centripetal force could be involved in this scenario, and also because this solution never seems to actually use the centripetal acceleration; it just keeps
So, my question is, why is centripetal acceleration involved in the
F = ma equation here? Am I missing something to do with the proton in this problem?
