Five point charges are located on the y-axis. Two are positive with charge q = 0.54 mC and three are negative with charge q = -0.54 mC
Five point charges are located on the y-axis. Two are positive with charge q = 0.54 mC and three are negative with charge q = -0.54 mC. The positive charges are a =4.5 m away from the origin, one on each side of it. Two of the negative charges are 2a away from the origin, one on each side of it. A negative charge sits at the origin. A positive point charge with charge Q= 6 mC is positioned on...

1)
A positive 3.4 x 10-9 C charge is brought in from
infinity to a point (2m,0). How much work did you do to move the
charge to this position?
W = 0 J

Now another positive charge 3.4 x 10-9 C is moved
from infinity to the coordinates (1m,2m). How much additional work
did you do to bring in the second charge? (The original charge is
held in place.)
W = 4.65*10^-8 J
Finally, a negative 3.4 x...
