How u recognize the surface charge density of these sheets are twice,once
sir,please clear this concept...
Sir while resolving tension for balloon it is seen that the tensions due to block and balloon are such that the two ends of string are being pushed.
Will it not result in coiling or accumulation of rope. Because i think tension on the same string should be in opposite direction for equilibrium.
And this was only told in NLM
chapter-electric charges and fields, topic-4 dielectrical constant (que-9 why we take v sigma g - v rho g)
Sir,charge k units k bare me kuch bataye...jase ki esu,emu,faraday
