Twelve identical point charges are equally spaced around the circumference of a circle of radius 'R'. The circle is centered at the origin. One of the twelve charges, which happens to be on the positive axis, is now moved to the center of the circle.
Find the magnitude of the net electric force exerted on this charge.
Express your answer in terms of some or all of the variables q, R, and appropriate constants.
Find the direction of the net electric force exerted on this charge.
Express your answer as an integer.
The Attempt at a Solution
- i drew the diagram of a circle with radius R and one of the 12 points at the center.
- i am fairly certain i need to use the principle of superposition but with 11 other points I am not sure where to start
- didnt attempt yet because need part A first.
Any help at all would be appreciated I am so confused!
