Electrostatics - Potential doubt
Their effect essentially cancels out since the potential due to those induced charges doesn't depend on their distribution. You take distance from centre right? Consider the induced charges, and write down the potential terms. They will cancel out.

Yeah, but unless there's a sum, you wouldn't get any kind of e there??

Fluid Mechanics effective gravity
Oh, I understood it. It's ridiculously simple once you understand the phrasing.
Generally, if you have a cylinder, the cross section is a circle. All they mean is, take a cylindrical vessel, and cut it obliquely such that the opening is a slant ellipse.
When you fill water, it'll only fill till the lowest point of the ellipse, but if moved with some acceleration, the surface of the water will shift to form a slope. We need the acceleration such that the slope of the liquid surface is coincident with the slope of the oblique cut.
