Q5
A positive charged particle is kept on the plane surface. There are two
points X and Y lies on the plane surface as shown above. If the point Y
is three times as far away from Q as point X. What is the ratio of the
electric force that would act on a small charge placed at point Y
compared to the charge placed at point X?
