A) \[\cot \,\text{ }\!\!\theta\!\!\text{ }\]
B) \[\cot \,\text{ }\!\!\theta\!\!\text{ }\]
C) \[\tan \,\text{ }\!\!\theta\!\!\text{ }\]
D) \[\sin \,\text{ }\!\!\theta\!\!\text{ }\]
Correct Answer: C
Solution :
In equilibrium \[T\,\,\cos \,\theta =mg\] ?.(i) and \[T\,sin\,\theta =F=Eq\] \[T\,sin\,\theta =F=Eq\] ?.(ii) \[\therefore \] \[\frac{T\,\sin \,\theta }{T\,\cos \,\theta }=\frac{\sigma q}{2{{\varepsilon }_{0}}\times mg}\] \[\tan \theta =\frac{\sigma q}{2{{\varepsilon }_{0}}mg}\] or \[\sigma \propto \tan \theta \]You need to login to perform this action.
