The distribution of electric charge in a thundercloud can be roughly approximated by several point like charges placed at different heights. Figure shows such an approximate charge dis- tribution consisting of a charge of +40 C at a height of 10.0 km and a charge of -30 C at a height of 4.0 km in the thundercloud. (a) What are the horizontal and the vertical components of the electric field that these two charges produce at a point P at a height of 10.0 km and at a horizontal distance of 6.0 km to the right? (b) What is the magnitude of this field at that point? Thundercloud charge distribution is approsimated by two point charges 60 km- +40C E2 10 km 9-30C 4,0 km To find the net electric field at P
