Electric Field

E = k q/r2 N/C E = F/q Electric Field For point charges: The force felt by a positive charge divided by the magnitude of the charge. E = F/q For point charges: E = k q/r2 N/C

What is the Field 2m to the right of a 3μC positive charge? X + 2m

What is the Field in the middle of the Charges? - 2μC X + 1m 1m

Where is the Field zero? 3μC - 2μC + 2m

Where is the Field zero? 3μC + 2μC + 2m
