One end of a massless rope, which passes over a massless and frictionless pulley P is tied to a hook C while the other end is free. Maximum tension that the rope can bear is 360 ~N . With what value of maximum safe acceleration (in ms ⁻² ) can a man of 60 ~kg climb on the rope?

Options

  1. A16
  2. B6
  3. C4
  4. D8

Correct answer

C. 4

Step-by-step solution

T -60 ~g =60 a ; T =3000 ~N ; a =4 ~ms ⁻²
