I want to prove coulomb's low for a single charge point from the general form of coulomb's low:(adsbygoogle = window.adsbygoogle || []).push({});

E→=1/(4∏€) ∫∫∫ ρv(ŕ) * (r→- ŕ→)/│(r→- ŕ→)│^3 dŕ

using Dirac Delta function

where r→ is the field point vector

ŕ→ is the source point vector

ρv(ŕ) is the volume charge density

I really don't know how to do it . I tried a lot but couldn't do it so can u help me please as soon as possible.Just guide me how to do it.
