Draw a LINE from the top-most QUAdrant point of the Circle, downward by whatever distance [it won't need to be very long].  OFFSET it by one mile to each side.  Draw your 2-mile chord Line between the intersections of the two Offset results with the big Circle.  Offset or COPY the original Line by 1/4 mile distances to get your drop locations, and TRIM the results so they run only between the horizontal Line and the Circle.  The lengths of those will be the drops at those locations.

 

[The size of the big Circle looks like it's a circumference of the Earth.  If that's what it is, I assume you are aware that Earth is not perfectly spherical, but bulges outward some at the equator from the centrifugal force of rotation.  So your drop distances will be smaller near the poles than near the equator.  And of course, there is probably no place on earth where the surface perfectly conforms to that curvature for a distance of 2 miles.  I confess to being curious about the purpose....]
