Please help with part A and C, thank you so much.

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. P + q a a (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 chosen This answer has not been graded yet. (b) Find the location of one point (other than co) where the electric field is zero. O at P O at the center of the triangle O 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: ke.) V3 kq E = 2 X (d) What is the direction of the electric field at P due to the two charges at the base? to the left O to the right O upward
