A glass cone has a total charge Q distributed overits sloping surface uniformly.The sloping length isl .The energy required to bring up a test charge q from a very large distance to the vertex of the cone is ?

sir how to find it is the question.this requires integration.consider the cone to made of infinite concentic circles of uniformly varying radius and thickness.find the potential due to each small circle. sum up===integrate.find the answer
