Homework Statement
A thin ring of radius x carries a charge Q uniformly distributed around it.
Sketch garphs showing how the potential and the field vary along the axis (y) from its centre.
A small dipole of strength p is placed at the centre of the ring so as to point alonf th axix (going through the centre, so vertical). What force does the ring exert on the dipole?
Homework Equations
I had to first find the expression for the potential and the electric field.
The Attempt at a Solution
For the sketch, I am a bit struggling... shall I think about it as for a point charge ?
For the dipole, I think there is no force on it because all the components cancel out...
Thank you for helping me !
