Question 437288: The gravitational force F between two objects is inversely proportional to the square of the distance between the objects. If the force F is 1.62x 10^-6N when the objects are 25cm apart, what is the gravitational force when the objects are 35cm apart?

Since the distance differ 35-25=10 cm and the F is inversely proportional to the square of the distance the F will decrease by 10%5E2 or 100, therefore we divide the F by 100 and find the new gravitational force:
F%5B2%5D=%281.62%2A10%5E-6%29%2F10%5E2=%281.62%2A10%5E-8%29N.
