Question

The three charges Q1, Q2, and Q3 are located at (-a,0), (a,0), and (0,-d), respectively.

1. Assume that Q1 and Q3 are greater than zero and Q2 = -Q1. Select all true statements:

a) The work required to move Q3 from its present position to the origin is zero.

b) The electric field at the origin points solely in the positive y direction.

c) If Q3 is released from rest, it will initially accelerate to the right.

d) The electric potential at the origin equals Q3/(4πε₀d). (Recall that k = 1/(4πε₀d).)

e) The external work done to bring these charges to this configuration (form infinity) was positive.

f) The electric potential at any point along the y-axis is positive.

g) The force on Q3 due to the other two charges is zero.

2. Now, assume that Q1=1.3μC, Q2=-2.6μC, and Q3=3.5μC. a=1.2 cm and d=2.8 cm. Calculate the potential energy of the charge configuration. Answer in SI units.
