Question

Consider the magnitude of the electric field E(z) on the axis of a uniform ring of charge where electric field have largest value?
A. Z = 0
B. |Z| = infinity
C. 0< |z| < infinity
c. 0 < |z|

Answer 1

Answer:

so the field will have two maximas between plus infinity and minus infinity except at the point x = 0 , so option c is correct.. I have used the variable x instead of z.. hope this helps..
