The problem asks for the electric potential due to a uniformly charged ring at a point along its axis.
To solve this problem, you will need to use the formula for the electric potential of a ring of charge, as well as the superposition principle to sum the contributions of each infinitesimal element of the ring.
Yes, you will need the formula for the electric potential of a ring of charge, V = keQ/r, as well as the integral form of the superposition principle to sum the contributions of each element.
It is recommended to break the ring into infinitesimal elements and integrate along the axis to find the total electric potential at the given point.
Yes, you can check your answer by calculating the potential at different points along the axis and comparing it to the known equation for the electric potential of a ring of charge.
