Problem

A +1 μC+1\,\mu\text{C} charge is at the origin. Identical charges of +1 μC+1\,\mu\text{C} are placed at (0,2 cm)(0,2\,\text{cm}) and (2 cm,0)(2\,\text{cm},0). Calculate the angle of the net force on the origin charge measured from the negative xx-axis toward the negative yy-axis. (a) 135∘135^{\circ} (b) 45∘45^{\circ} (c) 225∘225^{\circ} (d) 90∘90^{\circ}
