Two ocean liners, each with a mass of 42,000 metric tons, are moving on parallel courses, 93 m apart. what is the magnitude of the acceleration of one of the liners toward the other due to their mutual gravitational attraction? treat the ships as particles.

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
