It seems to me that the answers in the test suite are incorrect. They were calculated with an R in the denominator rather than R^2.
It seems to me that William is right...
It seems the problem is actually requesting the electric potential energy instead of the eletric force. Please, fix the test suite or change the name of the problem and its description. https://sciencing.com/calculate-electric-potential-energy-7821281.html
Thank you for pointing out the error!
As @Rafael pointed out, I will adjust the problem description accordingly.
