PLEASE HURRY!
If I have two dumbbells, one 10 lb the other 50 lb roll down equally steep ramps. The gravitational force acting on each one is proportional to their mass. Which one would reach the bottom first?
1. the 10 lb
2. the 50 lb
3. They would be the same

Explanation:

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
