Answer:
Acceleration of the ship,
Explanation:
It is given that,
Mass of both ships,
Distance between two ships, d = 110 m
The gravitational force between two ships is given by :
F = 8.38 N
Let a is the acceleration. Now, using second law of motion as :
So, the acceleration of either ship due to the gravitational attraction of the other is . Hence, this is the required solution.
