(II) Every few hundred years most of the planets line up

QUESTION:

(II) Every few hundred years most of the planets line up on the same side of the Sun. Calculate the total force on the Earth due to Venus, Jupiter, and Saturn, assuming all four planets are in a line (Fig.  ). The masses are \(M_{V}=0.815 M_{E}, M_{j}=318 M_{E}, M_{s}=95.1 M_{E}\), and their mean distances from the Sun are , and 1430 million , respectively. What fraction of the Sun's force on the Earth is this?
