Expert Solution

Step 1
Electric field due to a point charge:
The magnitude of the electric field due to a point charge at distance from it is defined by the equation,
where is the charge and is Coulomb's constant.
If the charge is positive, then the electric field moves away from it. If the charge is negative, then the electric field moves towards it.
NOTE:
Given:
Charges and
The distance of the charges and from point P is
