Answer:
0.324×10⁻³ m/s²
Explanation:
G=Gravitational constant=6.67408×10⁻⁸ m³/kg s
m₁=m₂=Mass of the ships=42000×10³ kg
r=Distance between the ships=93 m
The ships are considered particles
From Newtons Law of Universal Gravitation
∴Acceleration of one of the liners toward the other due to their mutual gravitational attraction is 0.324×10⁻³
