Answer:
The vector sum of the individual electric filed is 19.8 N/C
Explanation:
The principle of superposition states that every charge in space creates an electric field at point independent of the presence of other charges in that medium.
The resultant electric field is a vector sum of the electric field due to individual charges.
Let the electric field directed due north = N
Also, Let the electric field directed due east = E
then the resultant field = R
Given;
An electric field directed due north, N = 11.2 N/C
R² = N² + E²
R = √(N² + E²)
R = √(11.2² + 16.3²)
R = 19.8 N/C
Therefore, the vector sum of the individual electric filed is 19.8 N/C
