There is a charged particle, -2 nC, placed at (-1,-1). We wish to determine the electric field around this point charge, and place a probe at 3 locations:

a) Determine the electric field at coordinates (1 cm, -1 cm), call this point A

b) Determine the electric field at coordinates (-1 cm, 1 cm), call this point B

c)Determine the electric field at coordinates (1 cm, 1 cm), call this point C

d) Draw a diagram of this set up, with labels. Draw the three electric field vectors (using the length of the vectors to indicate field strength) on the diagram.
