Question

Three charges, q1 = 9.0 nC, q2 = 5.0 nC, and q3 = –3.0 nC are arranged in a right angle triangle as shown in the diagram. The distance between q1 and q2 is r12 = 6.0 cm, and the distance between q2 and q3 is r23 = 3.0 cm. Positive x is taken to the right and positive y is taken upward.

I can not upload the graph so q2 at (0,0) q1 at (-6,0) q3 at (0,-3)

question -----What is the magnitude of the net electric force exerted on charge q3 from q1 and q3? a) 2.6×10–4 N b) 1.5×10–4 N c) 1.9×10–4 N d) 1.1×10–4 N

Two point charges Q1 = 30.0 nC and Q2 =
-40 nC are held fixed along the x-axis. Q1 is at x = 0
and Q2 is at x = 72.0 cm. A third particle, of mass m =
2.2 x 10-6 kg, has charge Q3 = 42µC. If
Q3 is released from x = 28 cm, what is its initial
acceleration?

Three charges,
Q1, Q2, and
Q3 are located along a straight line. The
position of Q2 is 0.235 m to the right

m to the right of Q2. The force on
Q2 due to its interaction with
Q3 is directed to the (Give ALL correct
answers, i.e., B, AC, BCD...)
A) right if the two
charges are negative.
B) left if the two charges are positive.
C) right if the two charges have opposite...
