The three charges in the figure are q1Â = 68 micro coulomb, q2 =q3Â = -34 microcoulomb
a) what is the electric force on charge q1
b) what is the electric field created by the three charges a the point (x,y) = (2.0m, 1.0m)?
c) what is the electric potential at the point (x,y) (2.0 m, 1.0m)?
d) what is the potential energy of the system of three charges?
e) what is the amount of work required to bring an additional charge q = 1.0 micro coulomb from infinity to the point (x,y) = (2.0 m, 1.0m)
