The electric field at a point in space is defined as the force per unit charge at that point in space. We can write the electric field E of a charge q at a distance d from that charge, experienced by a charge Q, as E = F Q = k q d 2 . The electric field has a direction such that it points toward negative charges and away from positive charges. Suppose your rub a balloon in your hair and it acquires a static charge of −2 × 10−9 C. What is the magnitude of the electric field created by the balloon at a location 1 m due north of the balloon? Coulomb’s constant is 9 × 109 N · m2 /C 2 . Answer in units of N/C. You hair acquired an equal amount of positive charge when you rubbed the balloon on your head. What is the strength of the electric field created by your head at the location of your feet, 1.5 meters below? Answer in units of N/C.
