**1. Problem - Notes Jumbled, do not know if I am missing variables or not needed to answer the questions?**

Disclaimer: I am good at maths, fine with algebra and derivations, I just forget the formulae and units, especially when I haven't practiced things a lot, such as this topic (other subjects getting in the way...)

Diagram:

The variables I am given are d = 8cm cm, and V = 200 V, m = 2.86E-16. I have access to the mass and charge of an electron/ proton.

Here are the ten questions I need to be able to answer:

- Gravitational force on the particle
- Electrical force on the particle
- Electric field strength between... plates?
- The charge of the object
- Number of excess proton particles
**Power difference - changed to 201V:****The new field strength**

[*]The new electric force

[*]The net force

[*]The acceleration

[*]The time it will take from...

* The equations of motion.

* Electrostatic equations, such as E = V / d, E = F / q, V = w / q, Work done = Fd = qV = qED.

My apolegies, I was confused about numerous things, some are solved now, but I haven't done much since I started, but I still don't understand what other proton particles are being referred to.

Edit: Okay.

1. Gravitational strength? How is Gravity taking place here?

2. F = Eq but E = V / d

F = qV / d

= 1.6E-31 * 200 / 0.08

F = 4E-28 N

But I don't get the diagram, is that halfway, so it's 0.04? I know it's my diagram, but I thought this would be a common question.

3. E = V / d [?]

E = 200 / 0.08 [or is it 400 or 0.04 or both?]

E = 2500 N.C^-1 [Is this an overly high value?]

4. What object?.. I have a feeling this is my rubbish note-taking's fault. Maybe it wasn't an electron, in fact, I just realised the mass is about 10^15 times higher than an electron... I'm lost.## Homework Equations
