Three chargesare placed at the vertices of an equilateral triangle of side a = 0.93 m, as shown in. Charges 1 and 3 are +7.3 μC; charge 2 is −73 μC. (a) Find the magnitude and direction of the net force acting on charge 3. (b) If charge 3 is moved to the origin, will the net force acting on it there be greaterthan,less than, or equal to the net force found in part (a)? Explain. (c)Find the net force on charge 3 when it is at the origin.
