a) The magnitude of the electric field generated by a single point charge is given by

E=k (q)/(r^2)
where k is the Coulomb's constant, q is the charge and r is the distance at which we calculate the field.
Since we want to know the intensity of the field at distance of r=4.52 m from the charge of q=8.15 C, the intensity of the electric field is

E=k (q)/(r^2)=(8.99 \cdot 10^9 Nm^2C^(-2)) (8.15 C)/(4.52 m)=3.6 \cdot 10^9 N/C

b) Direction of the field
The charge that produces the field is negative, and we know that the electric field generated by a negative charge points toward the charge. Therefore, the direction of the electric field is towards the charge.
