Electromagnetism

I am having trouble in certain questions which involve the concept of earthing and potential among plates ! can you plz help by suggesting any methods about that? and 2nd ques, when we overflow a bottle we see the surface is not plane but curved ! what is the radius of that curve ? 3rd one there is a frustum of cone (which is formed by cutting half of a cone ) and one charge \(q\) is placed at the peak of original cone what is their force of interaction? I got \(\theta \frac { \sigma q\quad ln(2) }{ 2\pi { \E }_{ 0 } } \) where \(\theta\) is the half angle and \(\sigma\) is the charge density on the frustum. Am I right?

@Kishore S Shenoy it is just to s'y its v'lue is not going to 'ffect 'nswer 'nd it w's not even given in the question our interest lies only in the f'ct th't the cone is cut ex'ctly in h'lf Brilliant Member · 8 months, 1 week ago
