# 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 960 N.With what value of  maximum safe acceleration (in ms-2) can a man of 60 kg climb on the rope? Option 1) 16 Option 2) 6 Option 3) 4 Option 4) 8

As we learnt in

Motion of connected blocks over pulley -

Equation of motion for

Equation of Motion for

- wherein

:    T - 60g = 60 a

or    960 - (60$\times$10) = 60a

or    60a = 360

or    a = 6ms-2

Correct option is 2.

Option 1)

16

This is an incorrect option.

Option 2)

6

This is the correct option.

Option 3)

4

This is an incorrect option.
