In the following arrangement the system is initially at rest. The 5 kg block is now released. Assuming the pulleys and string to be massless and smooth, the acceleration of block is :-

Options:(select one or more)

Answer:

A, B, C, D

Solution:

$a_{A} - a_{B} = 2 a_{C}$

$5 g - T = 5 a_{A}$

$T - 10 g = 10 a_{B}$

$2 T - 8 g = 8 a_{C}$

The 10 kg block remains supported, so $a_{B} = 0$ .

$a_{A} = g /7, a_{C} = g /14$

All four relations are correct.
