Part 1
Three charges, Q1, Q2, and Q3 are located in a straight line. The position of Q2 is 0.235 m to the right of Q1. Q3 is located 0.125 m to the right of Q2. The force on Q2 due to its interaction with Q3 is directed to the.....
Right if the two charges are negative. A: True B: False
Right if the two charges have opposite signs. A: True B: False
Left if the two charges have opposite signs. A: True B: False
Left if the two charges are positive. A: True B: False
Left if the two charges are negative. A: True B: False
Part 2
In the above problem, Q1= 1.22·10-6 C, Q2= -3.03·10-6 C, and Q3= 3.33·10-6 C. Calculate the total force on Q2. Give with the plus sign for a force directed to the right. (in N)
Part 3
Now the charges Q1= 1.22·10-6 C and Q2= -3.03·10-6 C are fixed at their positions, distance 0.235 m apart, and the charge Q3= 3.33·10-6 C is moved along the straight line. For what position of Q3 relative to Q1 is the net force on Q3 due to Q1 and Q2 zero? Use the plus sign for Q3 to the right of Q1.
