Explain each step and Show me which formula do you use? Please do not just show the answer, I can not learn anything and use typing without Hand writting thank you

Two large parallel non-conducting sheets are spaced d 2.60 cm part and have a potential difference of magnitude 650 V. An electron is thrown directly away from one sheet, and is stopped just before reaching the other sheet. a.)

Explanation / Answer

a] v = sqrt(2E/m)

= sqrt(2*650*1.6e-19/9.1e-31)

= 15118578 m/s

b] E = V/d = 650/0.026 = 25000 V/m

c] we know that, E = sigma/eo

sigma = E eo = 25000*8.85e-12

= 2.2125*10^-7 C/m^2

positive,zero in order to make electrosatic force opposite to electrons motion

d] for E, straight line with zero slope,

straight line with zero slope,

   for V, straight line with positive slope

  straight line with zero slope,
