A monkey of mass $m$ is climbing a rope hanging from the roof with acceleration $a$. The coefficient of static friction between the body of the monkey and the rope is $\mu$. Find the direction and value of friction force on the monkey.
- Adownward, $F=m(g+a)$
- BUpward, F $= mg$
- CUpward, $F=m(g+a)$
- Ddownward, $F = mg$
