Which of the following has a largest net force a i c charge a distance of i m from a -2 c charge. a 1 c charge a distance of 0.5 m from a - i c chargc. a 1( charge exactly halfway between a -i c charge and a i c charge separated by 2 m. a i c charge exactly halfway between two -2 c charges separated by 2 m. a i c charge a distance of 2m from a -4 c charge. a 1c charge is placed at the origin with a 2c charge placed at the coordinates (2.0). where should a charge of -4c be placed such that the net force on that charge is zero at x< 0 at 0
