Question

Calculate the potential at a point on the perpendicular bisector of uniformly charged thin rod (linear density of charge =`lambda`) of length 2l at a distance a from the centre of the rod.

Answer 1

Correct Answer - `(lambda)/(4piepsilon_(0))In(sqrt(l^(2)+a^(2)+1))/(sqrt(l^(2)+a^(2)-1))`
