Thank you for your quick reply and sorry that 1. the link isn't working (i copied the link correctly but somehow it is not working) and 2. about posting in the wrong section...
Hi i would be glad if someone can help me on this.
I am having a bit of trouble in understanding why the upper limit of integration over "r" is infinity in the MIT open course material on Electric field page #16 by Prof Markus Zahn (material attached as a link to the pdf). Please help.
Thanks...
