My teacher would like us to use Newton's law of gravitational attraction to solve a question similar to this one:
"Two objects exert a force of gravity of 20N. One object's mass is increased by a factor of 5 and the masses are moved 6 times closer together. What force strength do they exert on each other now?"
This question is different from the one that my teacher assigned me so I can do that myself. My teacher would like us to solve it using an equation. Is he referencing to the universal gravitational constant to solve the question? How would you solve it?
