wrong !
We want force on a unit charge at distance R
think about Force = constant / R^2
what is the geometry with a constant radius R ??? !!!
A point charge is placed at the origin an x, y coordinate grid. Then, a curve is drawn to connect all the points in the xy plane where the electric field has magnitude 1.0 N/C. What best describes the curve?
A. a wide loop that passes through the origin
B. a circle centered at the origin
C. a straight line of infinite length through the origin
D. a straight line of finite length that doesn't pass through the origin
(My guess is that the answer is either C or D.)
