## Homework Statement

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

## Homework Equations

to be honest I am not too sure where to go after:

V= -⌠E.dl

any guidance at all would be much appreciated!thanks
