Please see attachment.

I really need someone to check this properly please- I know this is meant to help people but checking this would be a huge help to me since its worth marks....(Ive done all the work)

THANKS A LOT to anyone who helps..

2. Relevant equations

3. The attempt at a solution

a) C=[tex]\epsilon[/tex]_{0}*A/d

C=Q/V

0.1*10^-6=150*10^-6/V

V=1500V

C[tex]\propto[/tex] A

C[tex]\propto[/tex] 1/d

C=.1/4

C=.025uF

b)

q_max=C[tex]\epsilon[/tex]

q_max=.01*10^-4C

q(t)=q_{max}*(1-e^{-t/RC}

7*10^-7/0.01*10^-4=1-e^{-(t/1*10^-3)}

t=1.2ms (just used solver for this)

c)

U=0.5CV^2

U=0.32J

[tex]\Sigma[/tex] C=6uF

U=0.5CV^2

0.32=6*10^{-6}V^{2}

V=326.6V
