Calculating Capacitance of Two Electrodes with Varying Distance

AI Thread Summary
The discussion focuses on calculating the capacitance of two electrodes with different distances. The formula used is C=εA/d, with specific values for area (A) and distances (d) for each electrode. The participants confirm that the approach is correct and suggest that the two capacitances should be treated as being in parallel. The overall capacitance can be found by adding the two capacitance values together. The conversation concludes with a request for further assistance on a related topic.

Can I get some help in answering this questions?

As I understand, for two electrodes:

C=εA/d

A = 0.012 m2
d = 0.001 m on the left and d = 0.002 m on the right.

Thus the capacitance of each part is:

Left: C = (εx0.012)/0.001

Right: C= (εx0.012)/0.002

Firstly, is this the right approach? Secondly, what next? Do you simply add the two values to get the overall capacitance?

Help greatly appreciated!

Yes :oldsmile:

Follow the hint. Can you consider these two capacitances as being in parallel or series? If so, which one?
 
To me, they look to be in parallel. Hence C = C1 + C2. Correct?
 
Yes. That's right.
 
Great! Now if you can just turn your attention to my semi-infinite well question ... :wink:

Appreciate the help.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
