Three point charges, +q, +Q, -Q are placed at the corners ofan equilateral triangle. No other charged objects arenearby. The triangle is drew so that the +Q s at the bottomleft corner, the +q is at the top, and the -Q is at the bottomright corner.
a. What is the direction of the net force on charge +qdue to the other charges?
b. What is the total electric force on the system ofthree charges?
