Thanks for your explanation! But,What is meant by this line?

So is it correct to assume this world made up of only one type of charges(electrons)? Would the assumption that only one type of charges exist not affect Gauss Law?

I believe the answer is incorrect, reasons: The answer assumes that electric field will exist . But this is not the case , until and unless there is a bipolarity there cannot be an electric field ( in case of isolated charged objects, the field exists because the bipolarity is separated by a...

If an isolated conductor without cavities is charged, its excess charge will distribute itself on its surface in order to guarantee that the electric field is zero on its interior. If instead the conductor had an interior cavity, the charges would again distribute themselves on the outer surface...

Ok thanks! I can see things getting clear.. But,what actually prevents the electric field lines generated by external charge *to penetrate and get inside* the cavity throght the material of the conductor and make the electric field inside the cavity non-zero? this is my main doubt.

Suppose,we have a solid spherical conductor with a cavity in it and a charge +q placed outside the sphere.Then how is the electric field inside the cavity zero?Can you please explain this?

What is true is that the field due to the point charge outside of the conductor will not be able to penetrate the shell i.e. there will be no field due to the external point charge anywhere within the conductor nor in the cavity: the field will be **killed off*& by the charges on the outer...

My teacher taught me a formula for magnification in case of Compound Microscope, Magnification=(Angle Made By Object On Aided Eye)/(Angle Made by Object on Un-aided Eye) Can I use this formula for calculating magnification of Astronomical Telescope? Thanks!

Do Prism form image? If they do form image, then what is the nature of the image formed?

Is it possible to get a real image of virtual objects, If so please explain with examples and some real life situations? Look at my assertion "rays will not pass through virtual objects so how it can form real image", is this possible, please help.

About what second order term are you talking? Note: English is my second language. I will be thankful for any help!

<Moderator's note: Moved from a technical forum and thus no template.> $$\lim_{x\rightarrow 0} (x-tanx)/x^3$$ I solve it like this, $$\lim_{x\rightarrow 0}1/x^2 - tanx/x^3=\lim_{x\rightarrow 0}1/x^2 - tanx/x*1/x^2$$ Now using the property $$\lim_{x\rightarrow 0}tanx/x=1$$,we have ...

But doesn't 1^infty mean that we are multiplying 1 infinite times and hence the final product must be 1.

I've been taught that $$1^\infty$$ is undetermined case. Why is it so? Isn't $$1*1*1...=1$$ whatever times you would multiply it? So if you take a limit, say $$\lim_{n\to\infty} 1^n$$, doesn't it converge to 1? So why would the limit not exist?

Suppose light rays from an object fall perpendicular to the surface of the plane mirror. Will the image be formed at +infinity(a virtual image) or -infinity(a real image)? I will be thankful for help!
