need physics help, basically just need help with directions?

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
d2 .
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
1 × 10-9 C.
1. What is the strength 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/C2.
Answer in units of N/C.
2. What is the direction of that electric field?
1. south
2. east
3. west
4. north
5. upward
6. downward


3. 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.
4.
What is the direction of that electric field?
1. upward
2. south
3. west
4. north
5. downward
6. east
