What is the magnitude of the gravitational force exerted on Sirius A by Sirius B?

(You may use the following values:

  • Mass of Sirius A = 4.12×1030 kg4.12 \times 10^{30}\text{ kg}4.12×1030 kg
  • Mass of Sirius B = 2.04×1030 kg2.04 \times 10^{30}\text{ kg}2.04×1030 kg
  • Gravitational constant G=6.67×10−11 N m2 kg−2G = 6.67 \times 10^{-11}\text{ N m}^2\text{ kg}^{-2}G=6.67×10−11 N m2 kg−2)
