Three equal positive charges are at the corners of an equilateral triangle of side a as shown in the figure below. Assume the three charges together create an electric field. PA 9 a E = a a 9 (a) Sketch the field lines in the plane of the charges. (Submit a file with a maximum size of 1 MB.) Choose File no file selected (b) Find the location of one point (other than ) where the electric field is zero. o at p o at the center of the triangle at each vertex O at the center of the base (c) What is the magnitude of the electric field at P due to the two charges at the base? (Use any variable or symbol stated above along with the following as necessary: k.) (d) What is the direction of the electric field at P due to the two charges at the base? o to the left o to the right O upward o downward
