A ring of diameter 8.00 cm is fixed in place and carries a charge of +5.00 C

Question:

A ring of diameter 8.00 cm is fixed in place and carries a charge of +5.00 µC uniformly spread over its circumference.
(a) How much work does it take to move a tiny + 3.00-µC charged ball of mass 1.50 g from very far away to the center of the ring?
(b) Is it necessary to take a path along the axis of the ring? Why?
(c) If the ball is slightly displaced from the center of the ring, what will it do and what is the maximum speed it will reach?
