Answer:
c. Moon A is four times as massive as moon B
Explanation:
Let's assume the:
- mass of the object =

- mass of the moon A =

- mass of the moon B =

- distance between the center of masses of the object and moon B =

According to the given condition the object is twice as far from moon A as it is from moon B
- ∴distance between the center of masses of the object and moon B =

<u>As we know, gravitational force of attraction is given by:</u>

<em>According to the condition</em>
Force on m due to
Force on m due to



Gravitational acceleration is approx 9.8 m/s
Time is 7s
a=9.8 m/s
t=7s
a = d/t^2
therefore:
d = a * t^2
d = 9.8 * 7^2
d = 9.8 * 49
d = 480.2 [m]
