Three point charges are arranged so they form an equilateral triangle. Their x, y coordinates are q1 at (0,3cm), q2 at (0,-3cm) and q3 at (5.2cm, 0). Their charges are q1 = +3 μC, q2 = -3 μC and q3 = -6 μC. They have a mass of 2 grams each, and both q1 and q2 are fixed, while q3 is free.

a) In what direction does q3 move?
b) What is the magnitude of the force on q3?
c) What is the magnitude of the acceleration of q3?

Three point charges are arranged on a line. Charge q3=+5.00x10^-9C and is at the origin. Charge q2=-3.00x10^-9C and is at x=+4.00cm. Charge q1 is at x=+2.00cm. What is the magnitude and sign (+ or -) for q1 if the net force on q3 is zero?

1) Three charges, Q1, Q2, and Q3 are located in a straight line.The position of Q2 is 0.268 m to the right of Q1. Q3 is located0.158 m to the right of Q2. The force on Q2 due to its interactionwith Q3 is directed to the.....
True or False:
a) Left if the two charges are positive.
b) Left if the two charges have opposite signs.
c) Right if the two charges have opposite signs.
d) Left if the two charges are negative.
e) Right if the two charges are negative.

2) In the above problem, Q1= 2.07·10-6 C, Q2= -2.84·10-6 C, and Q3=3.18·10-6 C. Calculate the total force on Q2. Give with the plussign for a force directed to the right.
[answer to this is: 2.52 N}

3) Now the charges Q1= 2.07·10-6 C and Q2= -2.84·10-6 C are fixedat their positions, distance 0.268 m apart, and the charge Q3=3.18·10-6 C is moved along the straight line. For what position ofQ3 relative to Q1 is the net force on Q3 due to Q1 and Q2 zero? Usethe plus sign for Q3 to the right of Q1.

(please help with questions 1 and 3! thanks!)

q1=(5.00nC) {0.300m} q2=(6.00nC)

- q3=(-3.00nC)

Three point charges are arranged as shown in Figure. Find magnitudeand direction of the electric force on the particle at theorigin.

So far i have F12 and F13, i labeled q1=5.00nC; q2=6.00nC;q3=-3.00nC
F=Fx+Fy
But i'm not sure what the i^ and j^ are.

my question is how to i figure out the magnitude of F in the j^ andi^ ?
