Textbook Question
Chapter 12, Problem 35P
A uniform 5.0-kg ladder is leaning against a frictionless vertical wall, with which it makes a 15° angle. The coefficient of friction between ladder and ground is 0.26. Can a 65-kg person climb to the top of the ladder without it slipping? If not, how high can that person climb? If so, how massive a person would make the ladder slip?

I do not understand the process to answer the second part of question b. Please help me understand how to get there!
Rank the six combinations of electric charges on the basis of the electric force acting on 91. Define forces pointing to the right as positive and forces pointing to the left as negative.
Rank in increasing order by placing the most negative on the left and the most positive on the right. To rank items as equivalent, overlap them.
▸ View Available Hint(s)
[most negative
91 = +1nC
92 = +1nC
91 = -1nC
93 = +1nC
92- +1nC
93 = +1nC
-1nC
92- -1nC
93- -1nC
91= +1nC
92 = +1nC
93=-1nC

+1nC
92=-1nC
93=-1nC
91 = +1nC
2 = −1nC
93 = +1nC
