Two monkeys A and B are holding on the two sides of a light string passing over a smooth pulley. Mass of the two monkeys are `m_(A)= 8` kg and `m_(B) = 10` kg respectively `[g = 10 m//s^(2)]`
(a) Monkey A holds the string tightly and B goes down with an acceleration `a_(r) = 2 m//s^(2)` relative to the string. Find the weight that A feels of his own body.
(b) What is the weight experienced by two monkeys if A holds the string tightly and B goes down with an acceleration `a_(r) = 4 m//s^(2)` relative to the string.

Answer

(a) 80 N
(b) `(640)/(N) ` for both
