LC 1 Calculate the electric force on Q , due to - 5m + 4m Q 2 and Q 3 . Write down the net force's magnitude Q , = 70 n C Q. = 50nc Q 2 = 20nC and direction . 2 now a negative charge Qy has been added. Recalculate the net - 5m . 3m +4m force on Q, and remember that Qu is Q1 = 70 nc X Q: 50 nc Q2 = 20nc negative, so it will pull Q , towards it ! Qu = - 100n CO - 8 m 3 This time add your own charge, Qs = 15 nc, and place it somewhere quadrant 2 quadrant 1 in the 4th quadrant. make sure that the distances X ( x andy ) have two decimal quadrant 3 quadrant 4 places , and recalculate the net electric force on Q, due to all five charges ( magnitude and direction )
