Consider three charges q 1 , q 2 , q 3 each equal to q at the vertices of an equilateral triangle of side l. What is the force on a charge Q (with the same sign as q ) placed at the centroid of the triangle, as shown in Fig. 1.9? FIGURE 1.9

Force experience by the charge ‘Q’ in the electric field due to system of charges.
As all the charges are positive hance there would be net zero field at centroid would be zero.
