Asked by Gordon

Charge +Q = +7.10 nC is uniformly distributed along the right half of a thin rod bent into a semicirle of radius R = 3.60 cm, while charge −Q = −7.10 nC is uniformly distributed along the left half of the rod. What is the magnitude and direction of the electric field at point P, the centre of the circle?
