Two charges of -1.0 C and -2.0 C each are placed 1.00 cm apart. To experience electrostatic equilibrium, an electron should be placed:

A) 0.5 cm away from the -1.0 C charge
B) 0.5 cm away from the -2.0 C charge
C) Closer to the -1.0 C charge than the -2.0 C charge
D) Further from the -1.0 C charge than the -2.0 C charge
