Positive charge is uniformly distributed around a semicircle of radius a as shown in (Figure 1). Find the magnitude and direction of the resulting electric field at point P, the center of curvature of the semicircle. Figure P Q 1 of 1 Part I What would be the magnitude of electric field at P if the semicircle were extended to a full circle centered at P? Express your answers separated by a comma in terms of some, all, or none of the variables Q and a and the constants k and πT. ▸ View Available Hint(s) ΕΧΕΙ ΑΣΦ ? a x E₁ = Submit
