Question

I am trying to figure this thing out, but I'm not sure what Vis... Now we also know that the charge on a pair of parallel platesis proportional to the potential difference V, namely
q=CV.
We also know that the capacitance of two parallel plates is givenby
C=0A/d,
where 0=8.85×10-12 isthe permittivity of free space and d is the separationbetween the plates. Combine these equations and to get the force asa function of the potential. So now if you were to make a graph offorce (F) vs.V2/d2, the slope of thegraph would be

A) 0A/2
B) 0
C) E
D) C
Force is Newtons and d is meters, so it's something like N/m^2in the end, but I don't know the units of V. Please help:) I am trying to figure this thing out, but I'm not sure what Vis...

Explanation / Answer

Given : q=CV.
the capacitance of two parallel plates
C=0A/d,
where 0=8.85×10-12 isthe permittivity of free space and d is the separationbetween the plates. Combine these equations and to get the force asa function of the potential. So now if you were to make a graph offorce (F) vs.V2/d2, the slope of thegraph would be    B)0
Units of V is Volts
I hope it helps you
