Question

Three charges are arranged on a line as showed above. For each statement select true of false.

In the figure, R=1.1m, Q1=1.39x10^-6C, Q2 = - Q1, Q3 = -Q1. Calculate the total force on Q2. Give your answer with a positive number for a force directed to the right.

Problem 1 a) Three charges are arranged on a line as shown above. For each statement select true or false. If Q1 is positive, Q2 is negative and Q3 is positive, then Q2 MUST feel a net force to the right If Q1 is negative, Q2 is negative and Q3 is positive, then Q2 MUST feel a net force to the right B If Q1 is positive, Q2 is negative and Q3 is negative, then Q2 MUST feel a net force to the right. If Q1 is positive, Q2 is negative and Q3 is positive, then Q2 MIGHT feel a net force to the right Submit Answer Tries 0/6 b) In the above figure, R-1.1 m, Q13x106 c,2-Qi and Qs1. Calculate the total force on Q2. Give your answer with a positive number for a force directed to the right. Submit Answer Tries 0/6

Answer 1

Part A

.

Part A Part B Problem 2) Force on Q_2 due to Q_1 = k Q_1 Q_2/R^2 = 9 times 10^9 times 1.39 times 10^-6 times 1.39 times 10^-6/(1.1)^2 N = 14,37 times 10^-3 N Force on Q_2 due to Q_3 = K Q_2 Q_3/(2R)^2 = 9 times 10^9 times 1.39 times 10^-6 times 1.39 times 10^-6/(2 times 1.1)^2 N = 3,59 times 10^-3 N Net force = (14,37 + 3,59) times 10^-3 N = 17,96 times 10^-3 N along left Answer = -17,96 times 10^-3 N to right.

Part B
