A monkey of mass 15 kg is climbing on a rope with one end fixed to the ceiling. If it wishes to go up with an acceleration 1 ~m / s ^2 , how much force should it apply to the rope if rope is 5 m long and the monkey starts from rest?

Options

  1. A150 N
  2. B160 ~N
  3. C165 N
  4. D150 T 160 ~N

Correct answer

C. 165 N

Step-by-step solution

The mass of monkey =15 ~kg a=1 ~m / s ^2 For the motion of the monkey T-[15 g-15(1)]=0 Hence, T is tension in the string T=15 g+15 aligned T & =15(10+1)=15 11 & =165 ~N aligned
