Wo 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?

2 newtons

10 newtons

125 newtons

625 newton

Gravitational force is expressed using the equation F = G (m1) (m2) / (r^2), so increasing the distance between 2 objects by a factor of 5 would cause the force to decrease by a factor of 25, since the equation shows an inverse square relationship between F & r. Therefore, the answer would be 50/25 = 2 N.
