Two point charges are located at two vertices of an equilateral triangle as shown in the figure. a) Draw the electric field vectors at the third vertex and label appropriately. b) Where must a third charge -2q be placed so that the electric field at the third vertex be zero? Show work and express the distance from the vertex in terms of l. Draw the charge on the figure. c) Now that the three charges are in place, you place a fourth charge 3q at the third vertex. What is the net electric force on this charge?
