Question
Can somebody answer this physics question? Now we also know that the charge on a pair of parallel platesis proportional to the potential differenceV, 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) 0
B) 0A/2
C) E
D) C

Explanation / Answer
Now we also knowthat the charge on a pair of parallel plates is proportional to thepotential 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) 0 (B)0A/2 C) E D) C EXPLANATION: C = q/V C = *A/d {Stored Energy} = E = (1/2)*C*V^2 = = (1/2)*(*A/d)*V^2 = (1/2)**A*(V^2)/d {Force} = F = E/d = -(1/2)**A*(V^2)/(d^2) {Slope Of F Versus (V^2)/(d^2)} = -(1/2)**A .
