Physics-Please check and I need help
posted by Rachel Lynn C. .
Please help set this up-
A person goes into the electric field and has an object with a charge value of 4.2E-6C. At a distance of 10m from the object that's responsible for the elctric field, the person sees a force of 8.0N on the object they have.
What is electric field intensity?
What is electric potential at that point?
I'm totally confused-Would I start with f=kq1/r^2 and I have no idea for the second question-please direct me to at least the correct formula Thank you
