\(Mg = T \,cos \theta ……….(2)\)
\((1) / (2)\) કરતાં
\(Fe/Mg = tan\theta ⇒ Fe = Mg \,tan \theta ⇒ qE = mg\, tan\theta \)
\(q\,\, \times \,\,\frac{\sigma }{{{ \in _0}}}\,\, = \,\,mg\,\,\tan \theta \)
\(\therefore \,\,\,\sigma \,\, = \,\,\frac{{mg\,\,{ \in _0}}}{q}\,\,\tan \theta \)
તેથી \(\sigma \,\, \propto \,\,\tan \,\,\theta \)
