Trаveling thrоugh оur sоlаr system, а spacecraft with a mass of 4.00 × 105 kg maneuvers to avoid collisions. The spacecraft detects two asteroids. Asteroid 1 is located directly behind the craft at a distance of 5.00 × 108 m and has a mass m = 2.50 × 1020 kg. Asteroid 2 is 3.00 × 106 m directly in front of the craft and is twice as massive as asteroid 1 (M = 2m). What is the magnitude and direction of the net gravitational force on the spacecraft due to these two asteroids at this time?
