3. Three charges A, B and C are placed at the locations of a circle as shown in the figure below. The circle has a diameter of 2m. (Please work out all the resultant forces or electric fields to the horizontal i.e. parallel to the line OX)If Q₁ = -50µC, Q₂ = +30 µC and Qc = +20 µC, calculate the force exerted in magnitude and direction by the charges at A and B on the charge placed at
