Charge is uniformly distributed around a ring of radius R = 2.40 cm, and the resulting electric field magnitude E

is measured along the ring’s central axis (perpendicular to the plane of the ring). At what distance from the

ring’s center is E maximum?​

Answer:

We find the maximum by differentiating equation and setting the result equal to zero.

With R=2.40 cm,

we have z=1.70 cm.
