Physics Ninja looks at the problem of calculating the electric field from a ring and disk by integration. The ring and the disk are uniformly charged the field is calculated for a point on the axis.

Once you said it took you a while to get this, i knew i was at the right place. Cos people like you know how to explain it in the simplest of terms since you have been in our position before. Thank you. DOn't stop what your're doing

5:01, Why can we assume angle theta will be the same for any dq on the ring? If dq was to be exactly on the x axis, wouldn't theta be 0?

@Pomegrante460 5 ай бұрын

Would the total charge Q be the area of the disk, if so why would it be the area & not the volume?

Thank you sir

So if you have a semi circle? I ended up integrating with respect to sin theta since dq would change as theta increases

Are there any experiments video showing electric field due to ring? And is the ring always going to get uniformly charged if we try to charge it

@vaibhavgowda6725 2 жыл бұрын

If the ring is perfectly conducting/metallic then yes it will have uniform charge distribution regardless of how we charged it. Unfortunately I couldn’t find any videos showing field due to a ring irl.

Doesn't x change depending on the distance of the point we're choosing to calculate the electric filed for?

Hello friend, the video is very good, but I have a question with a similar exercise: I need to find the electric field at a known midpoint of 2 charged circular loops like the ones in the video (each with a different charge, both positive). I have to apply the formula that you show in the video for each of the circular loops, and then my question is: Should I add or subtract each of the results to obtain the electric field at that point? (taking into account that both charges are positive). Thank you so much

i have an exam tomorrow, please help!! how come in the first problem you integrated with respect to Q? when doing the same problem but with a vertical rod instead of a ring, i integrated with respect to y using lambda = Q/Y dQ = lambda * dY and plugging that in for q, which is how i was taught. because, they say, Q is not a geometric quantity. why did you integrate with dQ? how do i know when to integrate with respect to Q or Y? does the ring not still have a charge density lambda = Q/(2piR)?

How did you modify the new limits?, any video or explanation on that.

Which type of gussian surface we will take in order to find E field due to a hollow capsule like object which have both hemisphere and cylindrical symmetry?
