Question

Electric field intensity, E can be defined as the electric (Coulomb) force on a unit test (1C) charge. Find the electric field intensity at a distance, d from the center of a +Q charged proton. use k as Coulombe constant.

Answer 1

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.
