Question

As you move away from a positive charge distribution, the electric field:

Always decreases
Always increases
Must change
None of the above
please explain this thoroughly!

Answer 1

The electric field always decreases.

Step-by-step explanation:

The electric field due to a point charge is given by :

`E=(kq)/(r^2)`

Where

k = electric constant

q = charge

r = distance from the charge

It is clear from the above equation that as the distance from the charge particle increases the electric field decreases. As you move away from a positive charge distribution, the electric field always decreases. Hence, the correct option is (c) "Always decreases".
