What is the universal law of gravitation?
A. Every point mass attracts every other point mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
B. Every point mass repels every other point mass with a force proportional to the sum of their masses and inversely proportional to the square of the distance between them.
C. Every point mass attracts every other point mass with a force proportional to the sum of their masses and inversely proportional to the square of the distance between them.
D. Every point mass repels every other point mass with a force proportional to the product of their masses and directly proportional to the distance between them.
Answer: Every point mass attracts every other point mass with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
