Question

Two objects attract each other with a gravitational force of 50 newtons from a given distance. If the distance between the two objects is increased by 5 times, what will be the changed force of attraction between them? A. 2 newtons B. 10 newtons C. 125 newtons D. 625 newtons

Answer 1

2 n

Step-by-step explanation:

Answer 2

The gravitational force between two objects varies inversely with the square of the distance between them.

So if the distance is multiplied by a factor of 5, the force is multiplied by a factor of (1/5²).

New force = (50 Newtons) x (1/5²)

New force = (50 / 5²) Newtons

New force = (50 / 25) Newtons

New force = 2 Newtons (A)
