Solve the all parts of following question:
Question: A ring of diameter 7.00 cm is fixed in place and carries a charge of +5.00 µC uniformly spread over its circumference.
Part A: How much work does it take to move a tiny +3.20-µC charged ball of mass 1.10 g from very far away to the center of the ring? (Assume the ball is moved along the axis of the ring.)
J
Part B: What is the maximum speed it will reach?
m/s
