Step-by-step explanation:

Electric field intensity E is defined as the electric (Coulomb) force on a unit test (1 C) charge. Mathematically, it is given by :


E=(F)/(q)

The electric force is given by :


F=k(qQ)/(d^2)

Where

Q and q are electric charges

d is the distance between charges

The electric field intensity at a distance d from the center is given by :


E=(k(qQ)/(d^2))/(q)

So,


E=(kQ)/(d^2)

Hence, this is the required solution.
