5. Use the tape measure to determine r, the distance between the charge and a point the four potential lines (circles) you just drew. r= m 6. Calculate the potential using the formula V = k. 1²/1 Where k = 9 * 10⁹, q=1nC = -1 * 10⁹ and r is your reading from the tape measure. Note: We are using a rounded value for k to simplify the calculations. Here is an example of how to apply the measurements to the calculations. Given: q=-1nC= -1.00* 10-⁹℃ r = 0.269 m k=9.00* 10⁹ V = -32.9V N.m² C²

So I am doing this practice lab and I think I am just overthinking it for my step number 6. I sure it is as straight forward as it shows but I am just not understanding. So for "r" I have 84.7 cm which is 0.847 m for my first measurement. I think all I have to do is just input it to the formula provided that I have in the photo for step 6. So if i can just get a better example of what it is asking, I would greatly appreciate. I am just slow when it comes to following instructions.

5. Use the tape measure to determine r, the distance between the charge and a point on any one of the four potential lines (circles) you just drew. r= m 6. Calculate the potential using the formula V = k· Where k = 9 * 10⁹, q = 1nC = -1 * 10⁹ and r is your reading from the tape measure. Note: We are using a rounded value for k to simplify the calculations. Here is an example of how to apply the measurements to the calculations. Given: q=-1nC -1.00* 10-⁹℃ r = 0.269 m k = 9.00 * 10⁹ N•m² C² V = -32.9V Note: For this lab, V represents the actual potential Solution: Calculate the potential using the formula V = k v = (9.00 × 109 Nm). (-1.00 × 10-⁹C) 0.269m -33.5 = -33.5V
