(c)
Let T be the tension in the branch of a tree when monkey is descending with acceleration a. Then mg - T = ma; and T = 75% of weight of monkey
? ma = mg - (75/100) mg= (1/4) mg
or a =g/4.

(c)
Let T be the tension in the branch of a tree when monkey is descending with acceleration a. Then mg - T = ma; and T = 75% of weight of monkey
? ma = mg - (75/100) mg= (1/4) mg

As ma=mg _T ..so T=75%=2/3...

Now as a=g.

So put ma=mg ...mg=mg_2/3..mg cross on both sides ..so 1_0.75 ..as2/3 sequel to 0.75...so ans =0.25 or g/4
