See Hint
Right after the Big Bang, densities (and thus temperatures) would have been extraordinarily high—higher than anything we can reproduce in labs on Earth. We can develop models for what conditions were like back then and look at the way things are now to see if predictions from these models match our observations.
One major aspect that our models predict is that the four fundamental forces would have behaved differently under these extreme temperatures and then changed their behavior as the universe expanded and cooled. The table below shows how these forces behave in the universe as it is right now.
Use the information in this table to rank the relative strength of each force in order of decreasing strength for the two separate cases shown below.

Explanation / Answer
Case1
Forces at distances between a planet and a sun i.e, at very large distances
strongest to weakest
1.Gravitional force
2.Electromagnetic force
3.Strong nuclear force
4.Weak nuclear force
This happens because at large distances the nuclear force not operates.And electromagnetic force is more but nullify due to postive and negative forces but for gravitational force gets added up.
Case 2,
Forces at distances between particles in an atomic nucleus i.e,distances about the size of atomic nuclei
Strongest to weakest
1.strong nuclear force
2.electromagnetic force
3.weak nuclear force
4. Gravitational force
Strong nuclear force has the greatest strength over shortest range. Electromagnetic force is behind strong nuclear force by 2 orders of magnitude at the distances about the size of atomic nuclei.
