A circular ring of charge of radius a and total charge Q lies in the x-y plane with it center at the origin. The direction of the force on a very small segment of this ring is directed __________ if Q is negative.
a. inward toward the origin
b. outward from the origin
c. along the negative z-axis
d. in no direction since the force is zero
Thanks!

It's not clear what force you are referring to. If a positive charge were placed in the xy-plane and inside the ring, then it would experience no net force. If a positive charge were placed in the xy-plane outside the ring or anywhere above or below the xy-plane, it would be attracted to the ring. The force on the charge due to a very small segment of the ring would be towards the segment no matter where the charge was located, and we wouldn't know how that direction relates to the origin. There may be some information missing from your question.

Your question seems to be incomplete...
If it's complete, then perhaps 'd' is the Answer
