the electric field in a region is directed outwards and is proportional to the distance r from the origin Taking the electric potential at the origin to be zero the potential at a distance r a increases as one goes away from the origin b is proportional to r^2 c is proportional to r d is uniform in the region
I guess B.E=-(del V/del r), del V=-(E . del r), integrate both sides considering E=kr (as field is proportional to radial distance).Thus, V=k(r^2)/2.Thus proportional to r^2.Cheers!!
sorry buddy answer is ctell me if you get it
I found the same question online: As they donot allow external links in the answer so I’m unable to give u the direct link but u can enter “potential in a region where field is proportional to r” into Google and click the second link from the top (the one from topcoaching). Hope this helps. Let me know if u have an solution for C. Cheers!!
