1. The problem statement, all variables and given/known data

2. Relevant equations

E= kq/r^2

3. The attempt at a solution

K so looking at the graph, I noticed that there is a inverse-square relationship between the electric field and the radius/distance.

So I considered that there would have to be a curved slope on a 1/r^2 graph, because the x-axis is squared.

Wouldn't any graph have a curved slope when the x-axis is squared?

For example, a simple equation like y = x^2 results in a curved slope, because the y-axis point is always squared of the x-axis point.

Wouldn't that reasoning work with this?

So my answer is A.

But my friend is saying that the graph would be curved with just 1/r.

And straight with 1/r^2. So her answer is C.

Which is right? Other ppl in my class are also saying that the answer is C as well, but i dont see why.

A lot of people are saying I'm thinking too hard and reaching a wrong conclusion, but they don't know how to explain.

What's wrong with my theory and what's right about my friend's?

Please explain T__T
