Homework Statement


What is the electric field at a point when the force on a 1.20 µC charge placed at that point is

= (3.0 î -5.0 ĵ) × 10-3 N?

Homework Equations


E = KQ/d^2

The Attempt at a Solution


I'm having trouble visualizing the question. I attempted to draw it out, but its not making sense. Not asking for the answer, just an explanation of the problem. Thank you

Hi Benjamin and welcome to PF.

The equation you posted is not very relevant. What is another equation that directly relates force and electric field?

The answer gives the explanation in this case.Force and electric field are related by the formulae :F=QE .Using this you can calculate the electric field .
