The force of attraction due to gravity between two objects is f’. if the distance between the two objects doubles and the mass of one object triples, the new gravitational force between them will be — a. 0.5f’ b. 0.75f’ c. 1.5f’ d. 2.5f’

B. 0.75F'

Explanation:

The force due to gravity between two objects is:

F' = Gm₁m₂ / r²

where G is the gravitational constant,

m₁ and m₂ are the masses of the objects,

and r is the distance between them.

If r doubles and one mass triples:

G (3m₁m₂) / (2r)²

3/4 Gm₁m₂ / r²

3/4 F'

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
