Question

Consider a ring of radius R with the total charge Q spread uniformly over its perimeter. What is the potential difference between the point at the center of the ring and a point on its axis a distance 9R from the center? (Use any variable or symbol stated above along with the following as necessary: ke.)

Step 1

The radius of the ring,

The total charge spread uniformly,

The distance of the axis 9R from the centre of the ring,

Step 2

The potential difference between the point of axis and the centre of the ring,

The constant ke,

Step 3

The electric potential at th...
