1. The problem statement, all variables and given/known data An alpha particle of +2 elementary charge and mass 6.7*10^-27 can be given some speed by placing it at rest on the positive side of the parallel plate. Ignoring gravity effects what speed does the partial have when it reaches negative plate. 2. Relevant equations 3. The attempt at a solution my question is is this question solvable? i don't think so because the charge on capacitor or the separation between them is not given. could someone tell me if the question is solve able plz!!
