Question

According to Newton's Law of Universal Gravitation, if you triple the distance between two masses, the force they experience...

A.
becomes one-third of the original.

B.
will be nine times larger.

C.
becomes one-ninth of the original.

D.
will also triple.

Answer 1

Answer: C)

Explanation: This fact is related with the expression of the Newton's Law of Universal Gravitation given by:

F = G m1*m2/d^2

where G si the gravitational universal constant

d is the distance between masses

if we triple the distance, we have a resultant force dividing by 9 this means one-ninth of the original force.
