## Homework Statement

F = k(Q2*Q1)/(r^2)

## Homework Equations

## The Attempt at a Solution

I asked my teacher and he said that this is an inverse square law. Didn't say anything else. He also mentioned k is constant.

I assume i can plug in random values and see if there is a pattern... k=1 for all

Set 1, q1 = 2, q2 = 4, r = 5

F1 = 8/25

Set 2, q1 = 1 q2 = 5, r = 4

F2 = 5/16

I plugged in random values but i don't really get it.

What is inverse of what? I see that the r is squared and its below the kq1q2. I'm stuck.

Any advice is appreciated.
