It is said that the separation between two charges forming an electric dipole should be small. Small compared to what?
hii nikhil !
Good question...:- If you say that d is very small.....it doesn't mean that you are comparing d with any other parameter...it simply means that d is somewhat greater than zero...and has some value which is measurable.... in other word...smallest possible distance which cannot be zero and can be measurable...like 10^-2 mm or 10^-6 m .... These are some distance which can be considered as small....but infact you are not comparing these with some quantity .... Similarly if it says tha d is very large......it simply means...d is the largest possible no. close to infinty and measurable ....(can be measured with help of some scale) I hope this is clear to you now Regards Yagya
