You will use the Pythagorean Theorem to solve it.
c^2 = a^2 + b^2
c^2 = (1.5)^2 + (2)^2
c^2 = 6.25
c = square root of 6.25
c = 2.5

Answer:
![1.54481175\times 10^{-12}\ C](https://tex.z-dn.net/?f=1.54481175%5Ctimes%2010%5E%7B-12%7D%5C%20C)
Explanation:
= Permittivity of free space = ![8.85\times 10^{-12}\ F/m](https://tex.z-dn.net/?f=8.85%5Ctimes%2010%5E%7B-12%7D%5C%20F%2Fm)
A = Area = ![6\times 10^{-9}\ m^2](https://tex.z-dn.net/?f=6%5Ctimes%2010%5E%7B-9%7D%5C%20m%5E2)
d = Thickness = ![1.6\times 10^{-8}\ m](https://tex.z-dn.net/?f=1.6%5Ctimes%2010%5E%7B-8%7D%5C%20m)
k = Dielectric constant = 5.4
V = Voltage = 86.2 mV
Charge is given by
![Q=CV\\\Rightarrow Q=k\epsilon\dfrac{A}{d}V\\\Rightarrow Q=5.4\times 8.85\times 10^{-12}\times \dfrac{6\times 10^{-9}}{1.6\times 10^{-8}}\times 86.2\times 10^{-3}\\\Rightarrow Q=1.54481175\times 10^{-12}\ C](https://tex.z-dn.net/?f=Q%3DCV%5C%5C%5CRightarrow%20Q%3Dk%5Cepsilon%5Cdfrac%7BA%7D%7Bd%7DV%5C%5C%5CRightarrow%20Q%3D5.4%5Ctimes%208.85%5Ctimes%2010%5E%7B-12%7D%5Ctimes%20%5Cdfrac%7B6%5Ctimes%2010%5E%7B-9%7D%7D%7B1.6%5Ctimes%2010%5E%7B-8%7D%7D%5Ctimes%2086.2%5Ctimes%2010%5E%7B-3%7D%5C%5C%5CRightarrow%20Q%3D1.54481175%5Ctimes%2010%5E%7B-12%7D%5C%20C)
The charge on the outer surface is ![1.54481175\times 10^{-12}\ C](https://tex.z-dn.net/?f=1.54481175%5Ctimes%2010%5E%7B-12%7D%5C%20C)
Light travels in waves AND in bundles called "photons".
It's hard to imagine something that's a wave and also a bundle.
But it turns out that light behaves like both waves and bundles.
If you design an experiment to detect waves, then it responds to light.
And if you design an experiment to detect 'bundles' or particles, then
that one also responds to light.
