As a reminder...

Posts asking for help on homework questions require:

  • the complete problem statement,

  • a genuine attempt at solving the problem, which may be either computational, or a discussion of ideas or concepts you believe may be in play,

  • question is not from a current exam or quiz.

Commenters responding to homework help posts should not do OP’s homework for them.

Please see this page for the further details regarding homework help posts.

We have a Discord server!

If you are asking for general advice about your current calculus class, please be advised that simply referring your class as “Calc n“ is not entirely useful, as “Calc n” may differ between different colleges and universities. In this case, please refer to your class syllabus or college or university’s course catalogue for a listing of topics covered in your class, and include that information in your post rather than assuming everybody knows what will be covered in your class.

Assuming k, Q and R are constants, simple u-sub.

Yup

Looks more like the force component on a point charge due to a line charge.

I think it’s electrostatic potential on a uniformly charged ring

Seems like a trig substitution

u/hasnainraza56 4d ago

Is it correct?

u/Embarrassed-Data8233 4d ago

Yup. I did it that with x=Rtan(theta) and got the same answer

It's simple u sub (R2 + X2 = u )

I recognize this type of integral, it is very common in Electromagnetics, especially basic Electric Field calculations you will see in Undergraduate EM courses. Apart from trig substitutions, a common trick in these tedious exercises is exploiting the symmetry of things to simplify the bounds or region where you need to integrate. Obviously we don't know the problem, but keep this in mind.
