Positive charge A of charge 0.1 mC is placed at the origin of axis x, charge B, also positive, but of magnitude 4 times greater than A is placed at x=24.3 cm. These charges if released will run away from each other, but they are kept in place by the third charge positioned somewhere on the axis x. Find the value of this third charge (in mC).
