Expert Answer

Step 1

(a)

Consider k will be the Columbo’s constant, q is the charge and r is the distance.

The formula for the electric potential is:

Physics homework question answer, step 1, image 1

 

Step 2

Since the electric potential is the scalar quantity. Therefore, the electric potential at origin will be:

Physics homework question answer, step 2, image 1

Step 3

(b)

The formula for the electric field is:

Since the electric field is a vector quantity. Therefore, the electric field at origin will be:
