Electric potential at the center of meter stick

Click For Summary
SUMMARY

The discussion focuses on calculating the electric potential at the center of a meter stick with two 3.00-μC charges positioned at each end. The formula used is V = kq/r, where k is the Coulomb's constant, q is the charge, and r is the distance from the charge to the point of interest. The user attempted to simplify the calculation by factoring out k/r but encountered discrepancies in their results, indicating potential calculation errors. The correct approach involves summing the contributions from both charges at the center, ensuring accurate values for k and r are used.

Two 3.00-μC charges are at the ends of a meter stick. Find the electrical potential for the center of the meter stick.



V=kq/r



I just want to confirm my answer here. What I did is solve this for both charges in the equation above using r = 0.5m q= 3.00 uC. So I factored out k/r since they were the same for both charges, summed the charges, and then multiplied by k/r. My number isn't coming out correct for some reason and I believe it may just be calculator error. Thanks!
