The Problem is as follows:(adsbygoogle = window.adsbygoogle || []).push({});

A ring of diameter 7.50 is fixed in place and carries a charge of 5.50 uniformly spread over its circumference.

A) How much work does it take to move a tiny 3.80 micro-columb charged ball of mass

2.00g from very far away to the center of the ring?

B) What is the maximum speed it will reach?

-- I honestly have no idea where to start with this problem.--
