Okay the second one is the third answer because something like M(a+g) where m is the weight a is the acceleration and g was 9.8 so I got 844.87 the first one I still cant figure it out.

In the book the examples they give have a charge to them, but they don't offer any help with this question because the don't list a charge of the electron

I just need an equation to get me started, the book does not list one that is useful. The example they give uses the equation V1 = Ke(q1/r1) the problem is I don't know q.

In the equations listed they are refering to a point charge which is different then that of 1.6*10^-19. If I were to use that in the equation it would not work. The point charge in the example is 5.00*10^-6 C
