Consider three point charges to be placed on a horizontal line, Q1 = +6 mC at x=9cm, Q2 = −15 mC at x=0cm, and Q3 = +4 mC at x= −2 cm.

a) Determine the work done on the charges to bring all three to the listed locations from infinity.

b) Determine if there is a location on the x-axis, other than infinity, where the total potential is zero.

c) Determine the value of the electric field at the location(s) found in part b.
