x * * + + | Refer to the figure above. A thin half circle of radius R has a uniform positive electric charge of Q distributed evenly over its length. We want to find the electric field at the center. First, predict the direction of the electric field. Give your answer in the number of degrees from the positive x axis counterclockwise (CCW). 70 degrees.
