Expert Solution
Step 1

Electric Field: Electric field at a point is defined as the electric force acting on a unit positive charge assumed to be present at that point. 

The magnitude of the electric field due to a point charge q at r distance from it is given by the formula.

E=kqr2

where k is Coulomb's constant.

 

The direction of the electric field:

The direction of the electric field due to a point charge is away from it if it is positive. And the direction of the electric field due to a point charge is towards it if it is negative. 

 

NOTE: 

k=8.99×109 N m2/C21 cm=10-2 m
