63 ·· It is theoretically possible to place a satellite at a position between the earth and the sun on the line joining them,
where the gravitational forces of the sun and the earth on the satellite combine in such a way that the satellite will
execute a circular orbit around the sun that is synchronous with the earth’s orbit around the sun.
(In other words, the satellite and the earth have the same orbital period about the sun, even though they are at
different distances from the sun. The satellite always remains on the line joining the earth and the sun.) Write an
expression that relates the appropriate circular orbital speed v of a satellite in such a situation to its distance r
from the sun. Your expression may also contain quantities shown in Figure 11-20 plus the gravitational
constant G.
