Three small charges q1, q2, and q are placed at the three vertices of an equilateral triangle with sides of length a in air. set the charges equal to q1 = q2 = q3 = -1 coulomb.

a. draw a simple sketch of this charge configuration. calculate indicate the total electric force vector on charge q3. what is the magnitude of this force (in mks units) and is it attractive or repulsive.
b. calculate and show the electric field vector at charges.
c. now change charge q3 such that q3 = +3 coulombs. repeat parts a, and b of this problem.
