Text: Semi-circular charge distribution
Find the electric field in units of N/C at the position indicated by the star in the image, given a semi-circular distribution of charge with a radius of curvature of 4.3 m and a linear charge density of 2.6 C/m. Write your answer in vector format without the units. To input a vector, you can write it in point pair format with angle brackets (like this: <y>) or you can use Cartesian format like this: xi + yj, with i and j instead of and N/C.
