Question

In the given figure a monkey of mass m is climbing up a rope hanging from the roof with acceleration a.
The coefficient of static friction between the body of the monkey and the rope is u. Find the direction
and value of friction force on the monkey.​

Answer 1

Answer:

NOTE: In the absence of friction between monkey and rope, monkey will slide down.  

So, There is some frictional force which helps to monkey stand in upward direction.  

Explanation:

Which can explain with the help of-

F-mg=ma  

F=mg+ma  

F=m(g+a) upwards
