(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

derive an expression for the electrical potential at a distance x measured along the axis from the centre of a circular ring of radius R on which a charge Q is uniformly distributed.hence derive an expression for the electric field strength at this point

2. Relevant equations

to be honest im not too sure where to go after:

V= -⌠E.dl

any guidance at all would be much appreciated!!!thanks

3. The attempt at a solution
