4) The diagram to the right shows three equal positive charges of 1.00 C each. Two charges are vertically separated by 6.00 cm, and another charge is 4.00 cm to the right of the midpoint between the first two charges. Find the electrostatic force on the charge at the right. a. First, redraw the diagram, adding a useful coordinate system and showing relevant angles, separation distances, and forces. b. Use Coulomb's law to find the magnitude and direction of the net force on the charge at the right. You will have to find two individual electrostatic forces and break them into components to add the vectors and find the net force. 3 cm 3 cm 4 cm +
